Signature Resizer

Why signatures need resizing

Almost every Indian exam and job application asks you to upload your signature: SSC, IBPS, UPSC, NTA, railways, state commissions, banks. The rules are usually strict: a small file (often 10–20 KB), JPG format, sometimes an exact size like 140 × 60 px. A phone photo of your signature is 2–4 MB and mostly empty paper, which is why it gets rejected.

Typical signature rules

How to do it here

1. Signature ≤ 20 KB is selected in the Exams deck.
2. Drop a clear photo or scan of your signature. If your form needs exact pixels, type them in the optional exact pixels boxes under KB size, or use SSC signature resize.
3. Hit Repixel it ✨. Check the bytes on the badge and download.

How to photograph your signature

• Sign three or four times on clean white paper with a black gel or ball pen; pick the best one.
• Photograph in daylight, phone held flat above the paper, no shadow from your hand or phone.
• Crop tight around the signature. On this page, drag the bright box after choosing a pixel size; less paper means crisper ink in the same KB.

Mistakes that get signatures rejected

• Signing in CAPITAL letters. Many notices say signatures in capitals won’t be accepted.
• Grey or yellow paper. Poor light makes white paper look grey; shoot near a window.
• Too much empty space. The signature ends up tiny and blurry after resizing.
• Faint ink. Pencil or light pens fade when compressed.
• Different signature at the exam. Sign the same way you’ll sign on exam day.

Your signature is personal. It’s processed on your own device and never uploaded.

Black and white vs colour

Some forms ask for a black-and-white signature, others accept colour. A photo of a signature on white paper is effectively black and white anyway, as long as the light is even. If your scan has a yellow or grey cast, retake it near a window; a clean white background also makes the file smaller, which leaves more of the KB budget for crisp ink.

Check the file before you submit

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.
