Exam PhotoWhy exam forms reject a photo or signature, and how to fix each case
There are two kinds of rejection. The form can refuse the file on the spot, or people can reject the application later because the picture is unclear. The second kind is the costly one.
The form refuses the file at once
This is a machine check. It is annoying but harmless, because you can fix it and try again.
| Message or sign | Usual cause | Fix |
|---|---|---|
| "Invalid file type" | The file is PNG, HEIC, WEBP or PDF | Save it as JPG. Renaming the file is not enough. |
| "File size exceeds" | More KB than the largest allowed | Reduce pixels, then quality. |
| "File too small" | Fewer KB than the smallest allowed | Start from the original and save at higher quality. |
| "Invalid dimensions" | Pixels outside what the form accepts | Resize to the pixels the notice gives. |
| The upload never finishes | A slow connection, or a file far larger than allowed | Make the file smaller first, then try again on a steady connection. |
The application is rejected later
This happens when a person or a checking system looks at the picture. The notices we read name these reasons:
- Unclear, blurred or smudged pictures. Named in the SSC, IBPS, SBI and NTA documents.
- A photo of a photo. SSC says applications where a pre-existing photograph is captured in the live photo will be rejected.
- Cap, mask, sunglasses, or a shadow on the face.
- A miniature signature. SSC names blurred and miniature signatures.
- Capital letters. IBPS and SBI do not accept a signature or handwritten declaration in capital letters.
- Photo and signature swapped. IBPS says such a candidate will not be allowed to appear for the exam.
- Edited or made-up photos. NEET's bulletin warns about photographs that look fabricated, hand-made or computer made.
- Someone else's signature or handwriting.
A two minute check before you submit
- Open each file and look at it at full size. Can a stranger recognise the face and read the signature?
- Check the file type ends in .jpg or .jpeg.
- Check the KB against your exam's range.
- In the form's preview, check that each picture sits in its own place.
- Keep the files. Many exams ask you to bring a matching printed photo on exam day.
If the form is already submitted
Look for a correction window. NTA announces one for its exams, but its bulletins say that some items, such as NEET's photograph, signature and impressions, cannot be corrected. That is why the check above matters.
Check the official notice before you upload. We read these rules in the documents named under Sources on 11 November 2026. A new notice can change them, and the form on the day is the final word. This site is not connected with any exam body.
