Official UPSC Photo & Signature Specifications (2026)
These specifications apply uniformly to all UPSC examinations including Civil Services (CSE/IAS), Indian Forest Service (IFoS), NDA & NA, CDS, CAPF, Engineering Services (ESE), Combined Medical Services (CMS), and all other UPSC-conducted exams. The portal enforces these rules during upload — uploading the wrong KB or format results in immediate rejection.

About This Tool — UPSC Photo Resizer & Triple Signature Generator
FataFatResize.in's UPSC Photo Tool is a free, browser-based utility built specifically for UPSC aspirants. Unlike generic photo resizers that require you to know exact pixel values and KB limits yourself, this tool comes pre-configured with the official 2026 UPSC specifications for photographs and triple signatures.
The tool has two core functions: the Photo Resizer handles your passport photograph — resizing, compressing, and converting it to the correct JPG format within the 20–200 KB limit. The Triple Signature Generator takes a single signature image and produces a UPSC-compliant output with three signatures stacked vertically, compressed to 20–100 KB, within 350–500 pixels.
Instant Processing
Upload your photo and download a compliant result in under 3 seconds. All processing happens immediately in your browser using the HTML5 Canvas API — no server queues, no waiting.
100% Private & Secure
Your photo never leaves your device. You can disconnect Wi-Fi after the page loads — the tool works fully offline. This is the strongest possible proof that your biometric photograph stays private.
Completely Free
No subscription, no watermark on output, no hidden charges, no login required. Process unlimited photos and signatures for any UPSC exam for free — forever.
Automatic Format Conversion
Upload PNG, WEBP, HEIC, or any common format — the tool converts everything to JPG automatically. Transparent backgrounds are filled with white, which meets UPSC's plain white background requirement.
Smart Compression
An iterative compression algorithm automatically finds the right JPEG quality level to bring your output file within UPSC's KB range while maintaining the sharpest possible image quality.
Works on All Devices
Fully responsive — works on smartphones, tablets, and desktops. No app installation required. Tested on Chrome, Safari, Firefox, and Edge on both Android and iOS.
How to Use This Tool — Step-by-Step Guide
📸 Tab 1: Photo Resizer
1
Choose Document Type
Select "Photo" for your passport photograph or "Photo ID" for your Aadhaar / Photo ID card upload. The requirements box updates with the correct file size range and file name for each type.
2
Select Dimension Preset
Choose "350×350 px (Recommended)" — this is the safe square size that passes UPSC portal validation. UPSC 2026 does not mandate exact pixel dimensions, but 350×350 px is the widely accepted safe minimum. You can also use 500×500 px or set custom dimensions if needed.
3
Set Target File Size
Select 100 KB or 150 KB as your target — this gives a comfortable margin within the 20–200 KB range. The tool's smart compression algorithm adjusts JPEG quality automatically to hit your chosen target. Avoid going above 200 KB (portal hard limit) or below 20 KB (portal minimum).
4
Upload Your Photo
Click the upload zone or drag and drop your image. Supports JPG, PNG, HEIC (iPhone), and WEBP up to 15 MB. The original file size is shown immediately and the compressed output size updates in real time as you adjust quality and zoom settings.
5
Adjust Face Coverage and Download
Use the Zoom slider to ensure your face covers at least 75% of the image (UPSC 3/4th face coverage rule). Both ear lobes must be visible. When satisfied, click the green Download button — the file saves as photo.jpg, which is the exact filename required by the UPSC portal.
✍️ Tab 2: Triple Signature Generator
1
Prepare Your Signature
Sign on a plain white sheet of paper three times, one below the other, using black ink. Scan or clearly photograph the signatures. Ensure even, shadow-free lighting. If you're uploading a single signature, the tool will replicate it three times vertically — either approach is acceptable.
2
Upload and Generate
Upload your signature image to the Triple Signature Generator tab. The tool automatically creates three vertically-stacked copies with proper spacing, compresses to 20–100 KB, ensures dimensions fall between 350–500 pixels, and applies a clean white background. The live preview shows the exact output.
3
Check the Status Badge and Download
The status badge shows "Compliant" in green if your output is within UPSC limits, or warns in red if the file size is out of range. Once compliant, click Download — the file saves as signature.jpg, the exact filename required by the UPSC application portal.

Common UPSC Photo Upload Errors & How to Fix Them
Critical
Photo Exceeds 200 KB
Problem: Studio and smartphone photos often exceed 500 KB–2 MB. The UPSC portal enforces a strict 200 KB maximum for photographs. Files above this are rejected instantly.
Fix: Set target file size to 150 KB in the Photo Resizer. The smart compression automatically brings your photo well within the 20–200 KB range.
Critical
Photo Below 20 KB
Problem: Over-compressing a photo to reduce file size can push it below the 20 KB minimum, which is also rejected by the portal.
Fix: Keep quality slider above 75%. Choose 100 KB as your target — never 10 KB for photos. The tool warns if output falls below 20 KB.
Critical
Wrong File Format (PNG, WEBP, HEIC)
Problem: iPhone photos save as HEIC. Screenshots save as PNG. UPSC only accepts JPG/JPEG — all other formats are blocked by the portal.
Fix: This tool converts any format to JPG automatically. Simply upload your PNG, HEIC, or WEBP and download a compliant JPG.
Critical
Signature Not Vertically Stacked
Problem: Many candidates arrange three signatures side by side (horizontal). UPSC specifically requires vertical stacking — one below the other. Horizontal arrangements are rejected.
Fix: Use the Triple Signature Generator tab. It automatically creates the correct vertical arrangement. Never arrange signatures manually in a photo editor.
Common
Face Coverage Below 75%
Problem: Photos where the face is too small or off-center may be rejected during manual verification. UPSC requires the face to cover at least 75% of the photo area (3/4th face coverage).
Fix: Use the Zoom slider in the Photo Resizer to crop in closer until your face fills most of the frame. Ensure both ear lobes are visible.
Common
Colored or Non-White Background
Problem: UPSC requires a plain white background. Photos taken outdoors, against colored walls, curtains, or patterned backgrounds are rejected during scrutiny.
Fix: Retake your photo against a plain white wall with good even lighting. This tool cannot change backgrounds — only resize and compress. For background removal, use a dedicated tool first, then bring the PNG here for white background fill.
Common
Signature File Size Out of Range
Problem: The signature has a stricter 20–100 KB limit (not 200 KB). Many candidates use the same settings as their photo and end up with a 120–150 KB signature that gets rejected.
Fix: Always use the dedicated Triple Signature Generator tab, not the Photo Resizer, for your signature. The generator automatically targets the 20–100 KB range.
2026 New
Live Photo Mismatch
Problem: UPSC 2026 captures a live photo via webcam or QR code during form submission. If your uploaded photo doesn't closely resemble your live capture (due to old photos, heavy editing, or someone else's photo), the form will not submit.
Fix: Always use a genuine recent photo of yourself. Do not use heavily filtered, altered, or old photographs. The uploaded photo must match your live appearance.
Who Should Use This Tool?
Civil Services (IAS/IPS/IFS) Aspirants
The most competitive exam in India. Your application photo and signature must meet exact technical standards. This tool ensures compliant uploads for Prelims, Mains, and all stages.
NDA / CDS / CAPF Candidates
Defence service examinations conducted by UPSC follow the same portal specifications. Use this tool for all UPSC-administered defence and police exam applications.
Engineering Services (ESE)
ESE candidates applying for technical central services use the same UPSC portal. Photo and signature requirements are identical — same tool, same presets.
Combined Medical Services (CMS)
MBBS graduates applying for CMS and other UPSC specialist service exams follow the same upload specifications. No separate tool needed.
Indian Forest Service (IFoS)
IFoS candidates often apply simultaneously with CSE. Since portal specs are identical, the same resized photo and triple signature are valid for both applications.
First-Time Applicants
New to UPSC applications? This tool handles all the technical requirements automatically. Just upload your photo, select your target KB, and download — no technical knowledge required.
Your Privacy is Our Priority
A passport photograph is sensitive biometric data. Combined with your signature and personal details, it can be misused if exposed. Here is a complete, transparent explanation of how this tool handles your data.
