The official PAN photo and signature rules
These are the rules on the Protean (NSDL) guidelines page for PAN applications, checked on November 11, 2026:
| File | Size | Resolution | Format and limit | In pixels |
|---|---|---|---|---|
| Photo | 3.5 × 2.5 cm (portrait) | 200 DPI, color | JPEG, up to 20 KB | 197 × 276 px |
| Signature | 2 × 4.5 cm (landscape) | 200 DPI | JPEG, up to 10 KB | 354 × 157 px |
The presets above set all of this for you, and write the 200 DPI into the JPG file. Each result stays under 20,000 or 10,000 bytes, so it passes whether the site counts 1 KB as 1,000 or 1,024 bytes. If the application screen shows a different limit, it wins: change the numbers here to match.
Common reasons the PAN upload is refused
- The file is too big. A phone photo is several MB; the limit is 20 KB for the photo and 10 KB for the signature. Resize it here first.
- It is not a JPEG. iPhone photos are often HEIC, and screenshots are PNG. This tool always saves a JPG, and it opens HEIC photos too.
- The size or DPI is wrong. A photo cut to the wrong shape, or saved at a different DPI, can be rejected or come out squashed on the card. The presets give the exact size and DPI.
- Photo and signature are swapped. Upload the face photo in the photo field and the signature in the signature field. The file names this tool gives (with the size in them) help you tell them apart.
- The picture is unclear. Use a recent, sharp photo with your face straight to the camera and even light, and a signature in dark ink on plain white paper.
