White background (for forms & portals)
Tip: a signature photographed on plain white paper in good light gives the cleanest result. After downloading, use our 20KB signature resizer to match your portal's exact file-size limit.
Why remove the background from a signature?
A signature photographed on paper carries the paper with it — shadows, lines and grey edges that look unprofessional and can get an application rejected. A transparent PNG signature drops cleanly onto any document, contract or form, exactly like a digital signature. The white-background version is what most government and exam portals expect when you upload a signature image.
How it works
- Upload a photo or scan of your signature on plain paper.
- Adjust the strength slider if any paper shadow remains — the two previews update instantly.
- Download the transparent PNG for documents, or the white-background PNG for official portals.
Frequently Asked Questions
How does the background remover work?
It detects the paper colour in your photo and fades it to transparency based on how different each pixel is from the paper, keeping the ink strokes intact. Everything runs locally in your browser — no server ever sees your signature.
Which download should I use — transparent or white?
Use the transparent PNG when placing your signature onto a document, PDF or image. Use the white-background PNG when an official form or portal asks you to upload a signature photo.
My signature is in blue ink. Will it stay blue?
Yes. The tool preserves the original ink colour — blue, black or any other colour — in both downloads.
Can I make the signature exactly 20KB afterwards?
Yes — download your cleaned signature here, then run it through our free Resize Signature to 20KB tool to hit your portal's exact limit.
Is my signature uploaded or stored?
No. The processing happens entirely on your device with JavaScript. Close the tab and the working copy is gone.
