Quick answer

To resize a signature for an online form, upload your scanned signature, set the exact pixel size (e.g. 140×60) and KB limit (e.g. 10–20 KB) the form wants, and download. FitToKB locks both and shows a pass/fail check — free, in your browser, never uploaded.

Frequently asked questions

How do I resize a signature to 10–20 KB?

Upload your signature, set the width and height (commonly 140×60 px) and a target of 20 KB. FitToKB fits it under 20 KB and you can confirm it’s above 10 KB with the validator.

What format should a signature be?

Most forms require JPG. Sign in black ink on white paper for the cleanest result.

Is my signature uploaded?

No. It’s processed entirely in your browser and never uploaded — important for a sensitive image like a signature.

Which exams’ signature specs are built in?

SSC, UPSC, bank (IBPS/SBI), GATE, JEE and more — see the presets below for one-click setup.
