How do I make a signature for an exam form?
Choose your exam in the Exam preset menu above and upload your signature. This tool prepares the signature for exam form uploads in one step. It sets the correct KB range and pixel size for that exam, cleans the paper to white, crops the margin, and checks that the file is inside the minimum and maximum limit. When the status turns green, download the JPG and upload it.
Every exam has its own signature rules
A student filling three or four forms in one season can easily meet three or four different signature rules. A bank exam may want 10KB–20KB at 140 × 60 px. A medical entrance may allow up to 30KB. A civil services form may need a much bigger image with a minimum pixel size. If you use one file for all of them, at least one portal will likely reject it, sometimes only at the final submission step, when time is short.
This page brings those rules together. Each preset sets the file size range, the dimensions and a short note on ink and style. You can still change anything by hand, because notices are updated every year. The preset is a starting point, not a replacement for the official notification.

How to prepare your exam signature
- 1Select your exam
The KB slider, minimum box and pixel size update automatically. Read the short note under the menu.
- 2Upload your signature
Sign with a black ballpoint pen on white paper, photograph it, and upload.
- 3Check the preview
Make sure the full signature is visible, the background is white, and no strokes are missing. Use Rotate or Cleaning strength if needed.
- 4Download and upload
When the pill shows "✓ Valid", download the file. Name it clearly, for example "sign-ibps.jpg", so you do not mix up files for different exams.
Signature rules that apply to almost every exam
- Sign it yourself. The signature must be done by the candidate. A signature by a parent or anyone else can lead to cancellation.
- No capital letters. Many notices, including NTA and banking exams, say signatures in CAPITAL letters will not be accepted.
- Black ink on white paper is the safest choice everywhere. Some exams allow blue, but black is never wrong.
- Same signature everywhere. It will be compared with what you sign on the admit card, attendance sheet and during document verification.
- Only the signature. No date, no name below it, no stamp, and no extra lines.
- Keep the original. Save the source photo. If a later stage asks for a different size, you can create a new file from the original instead of re-compressing a compressed one.
Don't forget your photograph and documents
Most forms ask for the photo, signature and sometimes a thumb impression or declaration in the same step. Use Photo to 20KB or Photo to 50KB for bank and SSC photos. Use Photo to 200KB for NTA forms. Use Compress PDF to 200KB for certificates. If you just need a specific file size, the Signature to 10KB and Signature to 50KB tools are also available.
As with all PhotoKB tools, your signature is processed only in your browser and is never uploaded.
