Signature rejected: the seven reasons and how to fix each
Online form rejected your signature? Ink colour, dimensions, compression, and UPSC triple-signature rules — diagnosed one by one.
Start here: which of these is happening to you?
| Symptom | Likely cause | Jump to |
|---|---|---|
| Told to retake at counter | Background or face size | Cause 1 |
| Upload fails silently | Format or KB range | Cause 2 |
| Looks fine but rejected | Spec mismatch | Cause 3 |
Cause 1: Background or face size
Indian portals enforce a white background and minimum face height. A grey wall or small face in frame fails automated checks. See UPSC photo and signature size (including the three-signature rule) for the exact spec.
Cause 2: File format or size
Portals want JPG within a KB range — not PNG or HEIC. Check Signature rejected on an exam form — the real causes for upload troubleshooting.
Cause 3: Spec mismatch
Old studio sizes and outdated prints cause counter rejection. Cross-check the official notification.

When applicants retry without changing the underlying issue, the same rejection appears again — at the counter, in the upload validator, or during background verification. The fastest fix is to match your symptom to the spec before you retake or re-export. Indian passport and exam portals enforce pixel dimensions, background colour, face proportion, and file size together; fixing only one field often leaves the others failing.
If you are preparing for Passport Seva, start from the India passport photo spec and use the embedded tool to preview the compliance checklist before you submit. For exam forms, pick the preset that matches your notification year — specs change when a new advertisement is published, and older forum advice is frequently wrong.
Common mistakes we see in support tickets: exporting PNG when the portal accepts JPG only; shrinking file size so aggressively that the face becomes soft and fails manual review; using a square crop when the notification requires a portrait ratio; and relying on a studio print from before the 2026 ICAO migration. Each of these is fixable in one pass if you process on a desktop browser with a clear source photo.
Before you travel to the PSK or pay the application fee again, zoom to 100% on your export and check the background at the hairline and shoulders, confirm the chin-to-crown height fills the frame, and verify the KB readout sits inside the published window. Those four checks catch the majority of first-time rejections.
