Search traffic for NSDL PAN photo size, compress image for NSDL, and Protean PAN signature dimensionsspikes every tax season. The portal's validator is strict: wrong aspect ratio, missing DPI, or PNG format causes instant failure — often without a clear error message.

NSDL vs UTIITSL — Do Not Mix Specs
UTIITSL requires 213×213 px photos and different KB caps. If your link says tin-nsdl.com or onlineservices.protean, use NSDL specs. If it says utiitsl.com, switch to UTI dimensions. Our PAN Card Resizer supports both portals in one tool.
“Invalid Image” on NSDL — Quick Fixes
- Convert PNG/WebP to JPG
- Re-export at exactly 212×212 (not 213)
- Ensure file is under 50KB — 51KB fails
- Remove colour signatures — black ink only
