You can apply for a new PAN or a correction online through Protean (formerly NSDL e-Gov) or UTIITSL. If you choose to upload scanned images instead of using Aadhaar e-KYC, the photo and signature must meet strict rules. The values below are what the services have commonly published; always check the instructions on the site you apply through.
| Item | Protean (NSDL) | UTIITSL |
|---|---|---|
| Photo size | 3.5 × 2.5 cm, 200 dpi (this page: 197 × 276 px) | 213 × 213 px, 300 dpi |
| Photo type | Colour, JPG | Colour, JPG |
| Photo file size | Up to 50 KB | Up to 30 KB (check) |
| Signature | 2 × 4.5 cm, 200 dpi, black and white, JPG, up to 50 KB | Check the site |
Applying through UTIITSL? Keep KB size at your portal’s limit and change the optional exact pixels boxes under KB size to 213 × 213.
Sign on white paper with a black pen and photograph it in daylight. Open the Signature resizer, set KB size to 50 and type about 354 × 157 (4.5 × 2 cm at 200 dpi) in the optional exact pixels boxes under KB size.
Your ID photos are processed on your own device and never uploaded. The rules here were last checked on 5 November 2026.
After downloading, open the file’s details on your phone or computer (on Windows: right-click → Properties → Details; on Android: the file manager’s info button; on iPhone: the Files app’s info). You should see the same pixel size and a file size matching the badge. Then use the portal’s preview step: if the photo looks stretched or cut off there, go back, adjust the crop box and run again. Keep the downloaded file safe, because many portals ask for the same photo again at later stages, and your admit card will carry it.
For Protean (NSDL) online PAN applications with scanned documents, the photo has commonly been 3.5×2.5 cm at 200 dpi, colour, JPG, up to 50 KB. This page makes 197×276 px under 50 KB.
UTIITSL has used a 213×213 px photo at 300 dpi. If you apply through UTIITSL, set Pixels to 213×213 and KB size to 50.
Commonly 2×4.5 cm at 200 dpi, black and white, JPG, up to 50 KB. Use the Signature resizer with KB size 50.
With Aadhaar e-KYC, the photo usually comes from Aadhaar, so you may not need to upload one. Upload rules apply when you choose to submit scanned images.
