RRB Group D Photo Upload Problem — Fix Instantly (2026)
Getting a photo upload error on rrbapply.gov.in? This is the most searched issue from Group D applicants right now. Below are exact fixes for every error — file size errors, format errors, live photo not working, and camera permission problems.
Error: “File size should be between 50 KB and 100 KB”
Photo File Size Out of Range
Your photo is either below 50 KB or above 100 KB. The RRB Group D portal enforces both limits strictly and will not accept files outside this range.
- Select “Group D” → “Photo” on FataFatResize.in above
- Upload your photo — the tool auto-compresses to 50–100 KB
- Check the output KB badge — must show between 50 and 100
- If still below 50 KB, increase Quality slider to 90–95% and re-download
Error: “Invalid image dimensions”
Wrong Photo Size — Must Be Exactly 320×240 Pixels (Landscape)
RRB Group D is the only exam using landscape orientation (width wider than height). Studio photos, mobile photos, and selfies are all the wrong size and will be rejected automatically.
- Select “Group D” → “Photo” on FataFatResize.in — dimensions auto-set to 320×240 px landscape
- Upload any size photo — it will be resized to exact landscape dimensions automatically
- Use the Zoom slider to frame your face correctly within the landscape frame
Error: “Upload a JPEG” or “Invalid file format”
Wrong File Format — Portal Only Accepts JPG/JPEG
iPhone photos save as HEIC. Edited photos often export as PNG. Google Pixel photos sometimes save as WEBP. The RRB portal rejects all non-JPG formats.
- Upload your PNG, HEIC, or WEBP to FataFatResize.in — it converts to JPG automatically
- Download the .jpg output file and upload that to the RRB portal
RRB Group D Live Photo Not Working — Camera Not Opening
Fix Every Live Photo & Camera Permission Error on rrbapply.gov.in

- Page freezes during capture: Clear browser cache (Ctrl+Shift+Del), switch to stable Wi-Fi or 4G, reload and retry
Photo Rejected — “Coloured Background” or “Invalid Background”
RRB Group D Requires Plain White or Light Background
Dark walls, coloured curtains, patterned backgrounds, or shadowed backgrounds are rejected. The background must be plain white or very light-coloured.
- Retake your photo against a plain white wall or very light-coloured wall
- Ensure no shadows fall on the background behind you
- PNG photos with transparent backgrounds are auto-filled with white on FataFatResize.in
Correction Window Open: 5–14 March 2026. If you already submitted with a wrong photo or signature, log in to rrbapply.gov.in with your application number and use the correction option. Prepare the correct file on FataFatResize.in above and re-upload before 14 March 2026.
RRB Group D Signature Size 2026 — Complete Specification
The most searched question from Group D applicants is the correct signature size and ink colour. Here is the complete official specification for RRB Group D signature 2026 — pixel dimensions, file size, ink colour, background colour, and every rule that affects acceptance or rejection.
Ink Colour
Black or Dark Blue
- Handwriting style: Signature must be in running (cursive) handwriting. Block letters or printed capital letters are strictly rejected at the document verification stage — even if pixel dimensions and file size are correct.
- Background colour for RRB Group D signature: Plain white background only. Sign on white paper and ensure the scanned image has a white or very light background. Coloured, grey, or yellow-tinted backgrounds are rejected. If your scan has a coloured background, use your phone camera's document mode to auto-whiten it.
- Ink colour for RRB Group D signature: Black ink or dark blue ink — both are accepted. Do not use red, green, or any other coloured ink.
- Paper: Plain white A4 or bond paper with no lines, no watermarks, and no printed text in the background area where you sign.
- Consistency: Use your natural, consistent signature — the same one you will sign at the exam centre. Do not use a simplified version.
- How to resize: Click "Group D" above → click "Signature" card → upload your scanned JPG or PNG to FataFatResize.in → download the correctly sized 140×60 px JPG at 30–49 KB. PNG is converted to JPG automatically.
Critical: The 30 KB minimum is enforced by the portal. Signatures below 30 KB are rejected as "low quality" even if dimensions are correct. If your output is below 30 KB, increase the Quality slider to 85–95% and re-process on FataFatResize.in.

RRB Exam-wise Official Photo & Signature Specifications (2026)
Every RRB exam requires specific pixel dimensions and file sizes for photos and signatures. Uploading the wrong size causes instant rejection. Use the table below to find exact specifications for your exam, then use FataFatResize.in to resize before uploading to the portal.
| Exam | Photo Dimensions | Photo File Size | Signature Dimensions | Signature File Size | Format |
|---|
| RRB ALP | 240 × 320 px — portrait | 50 – 150 KB | 140 × 60 px (50×20 mm) | 30 – 49 KB | JPG / JPEG |
| RRB Group D ⭐ | 320 × 240 px — landscape | 50 – 100 KB | 140 × 60 px (50×20 mm) | 30 – 49 KB | JPG / JPEG |
| RRB NTPC | 240 × 320 px — portrait | 30 – 70 KB | 140 × 60 px (50×20 mm) | 30 – 49 KB | JPG / JPEG |
| RRB RPF / RPSF | 240 × 320 px — portrait | 30 – 70 KB | 140 × 60 px (50×20 mm) | 30 – 49 KB | JPG / JPEG |
| RRB JE | 240 × 320 px — portrait | 30 – 70 KB | 140 × 60 px (50×20 mm) | 30 – 49 KB | JPG / JPEG |
| RRB Technician | 240 × 320 px — portrait | 30 – 70 KB | 140 × 60 px (50×20 mm) | 30 – 49 KB | JPG / JPEG |
| RRB Paramedical | 240 × 320 px — portrait | 30 – 70 KB | 140 × 60 px (50×20 mm) | 30 – 49 KB | JPG / JPEG |
Important: Always cross-check with the official RRB notification PDF from indianrailways.gov.in before submitting. RRB Group D is the only exam using landscape photo orientation (320×240 px). All exams share the same signature specs: 140×60 px, 30–49 KB.
Key Technical Points
RRB portals validate pixel dimensions, file size, and format automatically. RRB ALP uses portrait 240×320 px at 50–150 KB (150 DPI minimum). RRB Group D uses landscape 320×240 px at 50–100 KB — note the photo orientation is landscape, but the Group D signature is still the same 140×60 px at 30–49 KB as all other exams. NTPC, RPF, JE, Technician, Paramedical all use portrait 240×320 px at 30–70 KB. All signatures must be in running handwriting — block letters are rejected. Signature DPI minimum is 100 for all exams.
How to Prepare RRB Group D Signature for Upload
Many Group D applicants are rejected during document verification not because of wrong pixel size, but because of wrong ink colour, wrong handwriting style, or a coloured background. Follow this exact process to prepare a signature that passes both the portal upload and the manual verification.
1
Sign on Plain White Paper with Correct Ink
Take a plain white A4 sheet with no lines or watermarks. Sign clearly in black or dark blue ink using running (cursive) handwriting. Leave a 1–2 cm margin around the signature. The signature should be roughly 5 cm wide and 2 cm tall to fill the 140×60 px frame well.
2
Scan or Photograph at 100 DPI Minimum
Scan with a flatbed scanner at 100 DPI or higher. On a phone, use your built-in camera app in document mode — this increases contrast and whitens the background automatically. Avoid yellow or dim lighting, which adds a tint that the portal will reject as a coloured background.
3
Crop Tightly Around the Signature
Before uploading to FataFatResize.in, crop the image so only the signature area remains with a small white margin. This ensures the signature fills the 140×60 px frame correctly without being too small or cut off at the edges.
4
Select Group D → Signature on FataFatResize.in
Click "Group D" in the exam pills above, then click the "Signature" card. The tool auto-loads: 140×60 px at 30–49 KB. Upload your cropped signature (JPG or PNG both accepted). PNG is converted to JPG automatically.
5
Verify KB Range and Download
Check the output KB in the preview badge — it must be between 30 KB and 49 KB. If below 30 KB, increase the Quality slider to 85–95%. If above 49 KB (rare for signatures), reduce quality to 70–75%. Download — file is named RRB_Group_D_signature_140x60.jpg.
Tip: The signature you upload must match the one you will sign physically at the exam centre. RRB Group D document verification is strict about signature consistency.

Common Photo & Signature Upload Errors
Most Common
Wrong Photo Orientation — ALP vs Group D
Problem: ALP requires portrait 240×320 px; Group D requires landscape 320×240 px. Using the wrong orientation causes instant rejection.
Fix: Always select your specific exam on FataFatResize.in first — dimensions and KB auto-load correctly.
Group D — Very Common
Signature Below 30 KB or Above 49 KB
Problem: Over-compression puts signature below 30 KB; large scans stay above 49 KB. Both are rejected by the RRB Group D portal.
Fix: On FataFatResize.in, keep Quality at 80–90%. If below 30 KB, increase to 85–95%. If above 49 KB, reduce to 70–75%.
Group D Rejection
Coloured Background on Signature
Problem: Yellow or grey background from coloured paper or poor lighting. RRB Group D requires white background for signatures.
Fix: Scan on white paper under good light. Use your phone camera's "document mode" to auto-whiten the background before uploading to FataFatResize.in.
Common
Block Letters in Signature
Problem: RRB Group D explicitly requires running (cursive) handwriting. Block or printed signatures are rejected at document verification even if file size and dimensions are correct.
Fix: Sign in cursive with black or dark blue ink on white paper before scanning.
Common
Wrong File Format (PNG, WEBP, HEIC)
Problem: iPhone photos save as HEIC; edited photos often export as PNG. RRB portals only accept JPG/JPEG.
Fix: Upload any format to FataFatResize.in — the tool converts everything to JPG automatically.
Easily Avoidable
Coloured Photo Background
Problem: RRB Group D (and all RRB exams) require a plain white or light background for photos. Dark or patterned backgrounds are rejected.
Fix: Upload your photo to FataFatResize.in — transparent PNG backgrounds are automatically filled with white. For coloured backgrounds, retake the photo against a white wall.
Privacy — Your Photo Never Leaves Your Device
Client-Side Only
All resizing, compression, format conversion, and DOP overlay on FataFatResize.in happens in your browser using HTML5 Canvas API. No remote server involved.
Zero Network Requests
After page load, no request carries your image data. Verify in DevTools (F12) → Network tab → process your photo → zero outgoing image requests.
No Storage or Logging
No database, no cloud storage. When you close the tab, all image data is wiped from memory. Nothing persists anywhere.
Works Fully Offline
Disconnect internet after FataFatResize.in page loads — the tool keeps working. This is the strongest proof your photo and signature data never leave your device.
RRB Live Photo — What It Is, How to Capture, & Common Problems (2026)
Many applicants search for "rrb group d live photo" or "rrb live photo." This section explains exactly what RRB live photo means in 2026, which exams require it, how to capture it correctly, and how to fix common errors on the portal.
Important — older guides have this wrong: RRB Live Photo is NOT simply uploading a recent passport photo. In many 2025–2026 notifications, it is a real-time photograph captured live via your device camera at the time of filling the online application on rrbapply.gov.in. Pre-saved or studio photos cannot be uploaded in these cases — the portal captures the image directly from your webcam or mobile camera.
What is RRB Live Photo?
RRB Live Photo is a real-time photograph taken via your device's camera — webcam on a laptop/PC, or the front/rear camera on a mobile — at the exact moment of filling the application form on the RRB portal. It is designed to verify your identity and prevent mismatches or fraud during CBT (Computer Based Test), document verification, or exam day.
Affected exams (2025–2026 notifications): RRB NTPC (Graduate & Undergraduate), RRB Technician, RRB Group D, RRB JE, RRB Section Controller, and other posts under CEN 02/2025, CEN 05/2025, CEN 06/2025. Always check the specific CEN notification PDF to confirm whether live capture is mandatory for your exam.
Lighting
Good, even lighting from the front. Avoid harsh shadows on your face, glare from overhead lights, and backlit setups (window behind you). Natural daylight facing you is ideal.
Face Position
Face straight toward the camera. Eyes open, neutral expression. Both ears should be visible. No sunglasses. Spectacles allowed only if worn regularly — no tinted lenses.
Background
Plain dark or plain-coloured background preferred. Avoid cluttered backgrounds. Avoid wearing white or very light clothing that blends into a light background and confuses face detection.
Camera Distance & Level
Hold or place camera at eye level. Suggested distance: 20–30 cm for mobile, standard webcam distance for laptop. Do not tilt or angle the camera — face should fill most of the frame.
Not Allowed
No caps, hats, or headgear (religious headgear is permitted). No heavy jewellery that covers the face. No masks. No edited or filtered photos — the system captures directly from your live camera feed.
Device & Browser
Use Chrome or Edge browser (latest version) for best compatibility. If your laptop webcam isn't working, the portal may provide a QR code — scan it with your mobile to capture via phone camera instead.
How to Capture RRB Live Photo — Step by Step
1
Open rrbapply.gov.in in Chrome or Edge
Go to the official RRB application portal — rrbapply.gov.in. Use Chrome (recommended) or Edge. Avoid Firefox or older browsers as camera permissions may not work correctly. Make sure your browser is updated to the latest version.
2
Allow Camera Permission When Prompted
When the application reaches the photo capture step, the browser will ask for camera permission — click "Allow." If you accidentally clicked "Block," go to browser Settings → Privacy & Security → Site Settings → Camera → find rrbapply.gov.in → change to "Allow," then reload the page.
3
Position Yourself and Follow On-Screen Prompts
Sit in good lighting facing the camera. Follow the on-screen instructions — the portal may show a face-outline guide to align your face. Wait for the face detection indicator to confirm alignment before capture triggers automatically, or click the capture button when prompted.
4
Review and Confirm
After capture, the portal shows a preview. Verify: face is clearly visible, no shadows, background is plain, expression is neutral. If acceptable, confirm and proceed. If not, use the retake option (usually 2–3 attempts available).
Common RRB Live Photo Problems & Fixes
Most Common
"Camera not detected" or Camera Not Opening
Cause 1: Browser camera permission is blocked. Fix: Click the camera/lock icon in the browser address bar → set camera to "Allow" → refresh the page.
Cause 2: Another app is using the camera. Fix: Close all other apps using the camera, then retry.
Cause 3: Laptop webcam is disabled. Fix: Use your mobile instead — scan the QR code shown on screen (if available) or open rrbapply.gov.in directly on mobile Chrome.
Common
Photo Rejected / "Face Not Detected"
Cause 1: Poor lighting — face is too dark or has shadows. Fix: Face a window or bright lamp. Light should be on your face, not behind you.
Cause 2: Face too far or too close to camera. Fix: Position at 20–30 cm. Your face should fill roughly 60–70% of the frame.
Cause 3: Wearing dark glasses or face partially covered. Fix: Remove glasses (or use clear lenses only), ensure full face is visible.
Portal Issue
Capture Freezes or Page Crashes During Photo Step
Cause: Slow internet or browser compatibility issue.
Fix: Use stable Wi-Fi or 4G. Clear browser cache (Ctrl+Shift+Del), reload, retry. If on laptop with poor webcam, switch to mobile Chrome with a good connection and scan the portal QR code if provided.
Mobile Issue
Mobile Camera Permission Not Working
Fix: Phone Settings → Apps → Chrome → Permissions → Camera → Allow. Then reopen rrbapply.gov.in in Chrome and retry the photo capture step.
RRB Live Photo vs. Document Verification Photo
| Stage | Photo Type | How Provided | Key Rules |
|---|
| Online Application | Live capture via camera | Real-time via rrbapply.gov.in portal | No pre-saved upload; captured live from device camera |
| Admit Card | Auto-printed from live capture | Downloaded from portal | Must match your appearance on exam day |
| CBT Exam Day | Identity via admit card photo | Verified by invigilator | Appearance must match live photo captured during application |
| Document Verification (DV) | Physical passport-size prints | Bring 4–8 prints to DV centre | Recent 35mm×45mm photo; use photo paper, not regular paper |
Note: FataFatResize.in is for resizing photos and signatures that require file upload — such as cases where a portal still accepts JPG uploads rather than live capture. Always check your specific CEN notification to confirm whether your exam requires live capture or file upload.
RRB Group D Signature Example & Sample Guide 2026
Many applicants search for "rrb group d signature example" and "rrb group d signature sample" to understand what an acceptable signature looks like before they scan and upload. This section covers what a valid Group D signature must look like, with clear examples of accepted and rejected styles.
ACCEPTED — Valid Signature
What a Valid RRB Group D Signature Looks Like
Style: Running (cursive) handwriting where letters are connected in a flowing manner. The signature does not have to be elaborate — even a simple cursive style with connected letters is accepted.
Ink: Black ink or dark blue ink (either is accepted). Signature is clearly visible and not faded.
Background: Pure white paper, no lines, no watermarks. The scanned image background is white.
Size in frame: The signature fills most of the 140×60 pixel frame — not too small (under 30% of frame) and not cut off at the edges.
REJECTED — Invalid Signatures
Common Signature Styles That Are Rejected
Block letters: "AMIT KUMAR" written in separated capital print letters — rejected. This is the single most common reason for signature rejection at document verification.
All capitals cursive: Even if the letters are connected but all uppercase like "AMIT" — may be flagged as block letters. Use mixed case cursive.
Single letter initial: Just an "A" or "AK" initial — not accepted as a full signature.
Pencil or light ink: If the signature is not clearly visible in the scan, it is treated as absent or forged.
Visual Guide — Correct Signature Placement on Paper
📄
Paper Setup Before Signing
Take an A4 sheet of plain white paper. Draw a light pencil box approximately 6cm × 2.5cm (slightly larger than the 50mm×20mm required area). Sign inside this box in running handwriting. Erase the pencil box after signing and before scanning — or use a ruler to mentally frame the area without marking it.
✍️
Sign with Your Natural Signature
Practice your signature 3–5 times on rough paper first. Use the same signature you will give at the exam centre — RRB cross-checks signatures. Do not create a "simpler" or "better" version just for the form. Your natural signature, however simple, is the correct signature.
📱
Scanning the Signature on Mobile
Place the paper under good lighting (natural daylight is best). Use your phone's built-in camera in "Document" or "B&W" mode — this increases contrast and removes yellow tinting automatically. Hold the phone directly above the paper to avoid angular distortion. Export as JPG or PNG, then upload to FataFatResize.in.
✂️
Crop Before Uploading to FataFatResize.in
Before uploading the scan to FataFatResize.in, crop it tightly around the signature — leave about 5mm of white space on all sides. A large white area around a small signature results in the signature appearing tiny within the 140×60 px frame after resizing. Tight crop = better result.
Quick Check Before Upload: Is your signature in cursive? Is the background white? Is the ink black or dark blue? Is the file between 30–49 KB after resizing on FataFatResize.in? If yes to all four — your signature is ready for RRB Group D upload.
RRB NTPC Photo & Signature Size — Complete Guide 2026
RRB NTPC (Non-Technical Popular Categories) has the same signature requirements as Group D but different photo specifications. This dedicated section covers all RRB NTPC photo and signature size requirements for 2026.
NTPC Photo — Dimensions
240 × 320 px
NTPC Photo — File Size
30 – 70 KB
NTPC Photo — Orientation
Portrait
NTPC Signature — Dimensions
140 × 60 px
NTPC Signature — File Size
30 – 49 KB
How RRB NTPC Photo Requirements Differ from Group D
| Requirement | RRB NTPC | RRB Group D |
|---|
| Photo Dimensions | 240×320 px (Portrait) | 320×240 px (Landscape) ⚠️ |
| Photo File Size | 30–70 KB | 50–100 KB |
| Photo Min DPI | 100 DPI | 100 DPI |
| Signature Dimensions | 140×60 px ✅ Same | 140×60 px ✅ Same |
| Signature File Size | 30–49 KB ✅ Same | 30–49 KB ✅ Same |
| Photo Format | JPG/JPEG ✅ Same | JPG/JPEG ✅ Same |
| Signature Ink | Black or Dark Blue ✅ Same | Black or Dark Blue ✅ Same |
Critical Difference: The only major difference between NTPC and Group D is the photo orientation. NTPC uses portrait 240×320 px; Group D uses landscape 320×240 px. Never mix them up. FataFatResize.in auto-loads the correct orientation when you select NTPC or Group D from the exam pills.
RRB NTPC — How to Resize Photo and Signature
Click "NTPC" in the exam pills above on FataFatResize.in. For the photo, the tool loads 240×320 px portrait at 30–70 KB. For the signature, click the Signature card — 140×60 px at 30–49 KB loads automatically. Both are processed entirely in your browser with no uploads.
Railway Group D Signature Problem — Fix & Troubleshooting Guide
This section addresses the most common railway Group D signature problems RRB applicants face — from portal upload errors to document verification rejections — and provides exact fixes for each issue.
Portal Error
Problem: "File size should be between 30 KB and 49 KB"
Cause: Signature file is below 30 KB or above 49 KB.
Fix for below 30 KB: On FataFatResize.in, increase the Quality slider to 85–95% and re-download. A 140×60 px JPG at 90% quality is typically 32–45 KB.
Fix for above 49 KB: Reduce Quality to 70–75%. Alternatively, ensure you selected "Signature" (not "Photo") — signature dimensions are 140×60 px, not the photo dimensions.
Portal Error
Problem: "Invalid image dimensions"
Cause: You uploaded your signature at photo dimensions (320×240 or 240×320), or you uploaded the photo at signature dimensions (140×60).
Fix: On FataFatResize.in, select your exam, then click the Signature card specifically before uploading. The dimensions auto-set to 140×60 px. Re-upload and re-download.
Portal Error
Problem: "File format not supported" or "Upload a JPEG"
Cause: You're trying to upload a PNG, WEBP, or HEIC file directly to the RRB portal.
Fix: Upload your PNG/HEIC/WEBP to FataFatResize.in — it automatically converts to JPG. Download the .jpg file and upload that to the RRB portal.
DV Rejection
Problem: Signature rejected at document verification
Cause 1 — Block letters: You signed in PRINTED/BLOCK letters. RRB mandates cursive/running handwriting.
Cause 2 — Mismatch: Your live signature at DV doesn't match the one uploaded. Always use your natural, consistent signature.
Cause 3 — Coloured background: Scan background is yellow or grey. Rescan with better lighting using your phone camera's document mode.
Upload Issue
Problem: Signature looks blurry or too small in preview
Cause: The signature was a small part of a large uncropped scan — it gets compressed into the 140×60 frame and appears tiny/blurry.
Fix: Before uploading to FataFatResize.in, crop the image tightly around the signature with 5mm margin on all sides. Then upload the cropped image.
Upload Issue
Problem: Page keeps showing error even after correct file
Cause: Browser cache or a stuck upload state on the RRB portal.
Fix: Clear browser cache (Ctrl+Shift+Del), use Chrome or Firefox, and try uploading again. Some applicants find that logging out and back in before uploading also resolves stuck portal states.
How to Change Signature After Submission in RRB Group D
Multiple applicants search for "rrb group d signature change" — this section explains when and how changes are possible:
Important: Once an RRB Group D application is submitted and the application window closes, signature changes are generally not permitted through the portal. However, during the application window, you can use the "Edit Application" or "Correction Window" feature if RRB announces one.
1
During Application Window (Before Final Submit)
If you have not yet done the final payment and submit, go back to the upload section of the form. Use FataFatResize.in to prepare the correct signature file, then re-upload. The portal will replace the old file. Always preview after upload to confirm the new file was accepted.
2
After Submission — Correction Window (5–14 March 2026)
RRB has opened a Correction Window from 5 to 14 March 2026. Go to the official RRB application portal, log in with your application number, and use the correction option to re-upload your photo or signature. Use FataFatResize.in above to prepare the correctly sized file before uploading.
3
After All Windows Close — Contact RRB Helpdesk
If no correction window is available, contact the RRB regional helpdesk via the official portal. Explain the signature issue with your application number. In some cases, the issue is resolved at the document verification stage by providing an explanation in writing.

Railway Signature Size in KB — All Exams 2026
Multiple applicants search specifically for "railway signature size," "signature size for railway group d," and "rrb group d signature size in kb." This section provides a comprehensive reference for all railway exam signature KB requirements in one place.
| Exam | Signature Width | Signature Height | Min KB | Max KB | Format | Ink Colour |
|---|
| RRB Group D ⭐ | 140 px | 60 px | 30 KB | 49 KB | JPG | Black / Dark Blue |
| RRB ALP | 140 px | 60 px | 30 KB | 49 KB | JPG | Black / Dark Blue |
| RRB NTPC | 140 px | 60 px | 30 KB | 49 KB | JPG | Black / Dark Blue |
| RRB RPF / RPSF | 140 px | 60 px | 30 KB | 49 KB | JPG | Black / Dark Blue |

| RRB Paramedical | 140 px | 60 px | 30 KB | 49 KB | JPG | Black / Dark Blue |
All RRB exam signatures share identical KB requirements: 30 KB minimum, 49 KB maximum, 140×60 px, JPEG format. The 30 KB minimum is enforced by the portal to ensure image quality — signatures below 30 KB are automatically rejected as "low quality." The 49 KB maximum prevents oversized files that the portal cannot process. Use the Quality slider on FataFatResize.in to dial in the exact KB — 80–90% quality typically lands in the 33–45 KB range for a 140×60 px signature.
All railway signatures in 2026 use the same specification: 140×60 px, 30–49 KB, black or dark blue ink, white background, cursive handwriting, JPG format. This is consistent across Group D, ALP, NTPC, RPF, JE, Technician, and Paramedical. Use FataFatResize.in to resize all of them for free.

Group D is the only RRB exam using landscape orientation (width greater than height). All other exams use portrait 240×320 px.

What happens if my Group D signature is below 30 KB or above 49 KB?
The RRB Group D portal enforces both minimum and maximum for signatures. Below 30 KB: rejected as "low quality image." Above 49 KB: rejected as "file size exceeds limit." Fix: on FataFatResize.in, if below 30 KB, increase the Quality slider to 85–95% and re-process. If above 49 KB (rare for 140×60 px signatures), reduce quality to 70–75%.
Can I upload a PNG or iPhone HEIC signature to FataFatResize.in?
Yes. FataFatResize.in accepts JPG, PNG, WEBP, and HEIC (iPhone) formats as input. It converts all formats to JPG for output automatically — because RRB portals only accept JPG/JPEG. Transparent PNG backgrounds are filled with white before conversion.
Can I resize both my Group D photo and signature in one session?
Yes, on FataFatResize.in. Select "Group D" — resize your photo (320×240 px, 50–100 KB) and download. Then click the "Signature" card — dimensions automatically update to 140×60 px at 30–49 KB. Upload your signature scan and download. No need to reload the page.
Does FataFatResize.in upload my photo or signature to any server?
No. FataFatResize.in processes everything locally in your browser using HTML5 Canvas API. Your photo and signature never leave your device. Verify in DevTools (F12) → Network tab → upload and process → zero outgoing image requests. The tool works fully offline after page load.
Is DOP required for RRB Group D?
Most RRB Group D online portal uploads do not require a DOP overlay on the digital photo. However, some document verification stages may require a dated photograph. Always check your specific official RRB Group D notification PDF. FataFatResize.in's "Add Name & Date" tab lets you add DOP in DD-MM-YYYY format if required.
Does FataFatResize.in work on mobile phones?
Yes, fully responsive. FataFatResize.in is tested on Chrome (Android), Safari (iPhone/iPad), Firefox, and Edge. You can upload photos and signature scans directly from your phone's camera roll. No app installation required.
What is RRB Live Photo — is a webcam/real-time photo required?
Yes, in many 2025–2026 RRB notifications, live photo capture is mandatory. RRB Live Photo means a real-time photograph taken via your device's camera (webcam on laptop or mobile camera) at the time of filling the application on rrbapply.gov.in. Pre-saved or studio photos cannot be uploaded in these cases — the portal captures live directly from your camera.
Affected exams include RRB NTPC, RRB Group D, RRB Technician, RRB JE, and others under CEN 02/2025, CEN 05/2025, CEN 06/2025. Guidelines: good lighting (face the light source), face straight, eyes open, neutral expression, plain background, no headgear (religious headgear permitted), no glasses with tinted lenses. Use Chrome or Edge browser and allow camera permission when prompted.
What does a valid RRB Group D signature look like?
A valid RRB Group D signature is in running (cursive) handwriting with connected letters, signed in black or dark blue ink on plain white paper. The signature should be roughly 5–6 cm wide and 2 cm tall on paper. Block letters, all-caps printing, and single initials are rejected. The scanned background must be white. The signature you upload to FataFatResize.in must match the one you sign physically at the exam centre and DV stage.
Can I change my signature after submitting the RRB Group D form?
After final submission, signature changes are only possible during the official Correction Window (5–14 March 2026). Log in to rrbapply.gov.in with your application number and use the correction option. Use FataFatResize.in to prepare the correctly sized signature file before re-uploading. After the correction window closes, contact the RRB regional helpdesk with your application number.
What is the RRB NTPC photo and signature size?
RRB NTPC photo: 240×320 pixels portrait, file size 30–70 KB, JPG format. RRB NTPC signature: 140×60 pixels, file size 30–49 KB, JPG format, black or dark blue ink, white background, cursive handwriting. The key difference from Group D: NTPC photo is portrait 240×320 px; Group D photo is landscape 320×240 px.
Why is my signature file below 30 KB even after resizing?
This happens when JPEG quality is too low, compressing the file below the 30 KB minimum. Fix: on FataFatResize.in, increase the Quality slider to 85–95% and re-process. A 140×60 px JPG at 90% quality is typically 35–45 KB. If still below 30 KB at maximum quality, ensure your signature is a clear, high-contrast scan — very faint signatures compress to tiny sizes.
