Applying for a PAN card online should take 10 minutes. Instead, thousands of applicants spend hours fighting cryptic portal error messages — all because their photo or signature file doesn't meet the exact pixel and KB requirements. This guide explains exactly what each portal requires and how to fix your files instantly.
Why Do PAN Card Uploads Get Rejected?
Both NSDL Protean and UTIITSL use automated validation scripts that check your image before a human ever sees it. These scripts verify three things:
- Exact pixel dimensions — even being 1 pixel off can cause rejection
- File size in KB — the portal hard-blocks uploads above the limit
- File format — only JPEG/JPG is accepted; PNG and WebP are rejected silently
NSDL (Protean) — Official Specifications
The Protean eGov portal (formerly NSDL) accepts scanned documents with these exact parameters:
NSDL Protean Requirements:
- Photo Dimensions 212 × 212 px (1:1 square)
- Photo Max File Size Under 50 KB
- Signature Dimensions 400 × 200 px (2:1)
- Signature Max File Size Under 50 KB
- Format JPEG / JPG only
UTIITSL — Official Specifications
UTIITSL uses a slightly different pixel count for photos and stricter DPI requirements for signatures:
UTIITSL Requirements:
- Photo Dimensions 213 × 213 px (1:1 square)
- Photo Max File Size Under 30 KB
- Photo Resolution 300 DPI
- Signature Dimensions 400 × 200 px (2:1)
- Signature Max File Size Under 60 KB
- Format JPEG / JPG only
The 212 vs 213 Confusion
NSDL requires 212×212 px while UTIITSL requires 213×213 px. Using the wrong dimension on either portal causes silent rejection. Always check which portal you are using before resizing.
Step-by-Step: How to Resize in 30 Seconds
- Open the OptiKit PAN Card Resizer — it works entirely in your browser, no uploads to any server.
- Select the correct tab — "PAN Photo" for your photograph, "PAN Signature" for your signature scan.
- Upload your image — drag and drop or click to browse. Any common image format works.
- Click "Generate PAN Ready Image" — the tool auto-crops to square, resizes to exact pixels, compresses under the KB limit, and injects proper DPI metadata.
- Download and upload to the portal — the output JPEG is guaranteed to pass validation.
Common Mistakes to Avoid
❌ Wrong Format
Uploading PNG or WebP files — portals only accept JPEG. Convert first.
❌ Using WhatsApp Photos
WhatsApp compresses photos to 72 DPI and strips metadata — guaranteed rejection on DPI-checking portals.
❌ Coloured Background
Both portals require a plain white or off-white background. Studio photos with grey backgrounds are frequently rejected.
❌ Printed Signature
Your signature must be handwritten in black ink on white paper and scanned — typed or digital signatures are rejected.
Photo Requirements Checklist
- Recent color passport photo (taken within 6 months)
- Plain white or off-white background
- Clear face visibility — no sunglasses, no hats
- Neutral expression, mouth closed
- Both ears visible
- No shadows on face or background
- Printed on matte finish photo paper (for scans)
