Resize Signature to 20KB
Forms that want a 20 KB photo usually want an even smaller signature, on a clean background. Scan or photograph your signature and this tool removes the paper, keeps the ink on a transparent background, and gets the file under 20 KB so the upload goes through. It all runs in your browser.

Frequently asked questions
Why won't my signature upload to the form?
Portals like UPSC, SSC and bank forms cap the signature file size — often 10–20 KB — and expect a clean background. A phone photo is usually far larger, so the upload is rejected.
Will the background stay transparent?
Yes. We lift the paper tone and keep a transparent PNG, so your signature sits cleanly on documents and certificates instead of inside a white box.
My scan has grey smudges — will it clean up?
Use the “paper removal strength” slider to push the background to fully transparent while keeping the ink.
Is it free and private?
Completely free, no watermark, and processed entirely on your device — your signature is never uploaded.
