About Signature Background Remover

Sign on a white paper, take a photo, and this tool turns it into a clean signature with a transparent background. You get a PNG file that you can place on documents without a grey or white box around it. It is free and runs in your browser, so your signature is never uploaded to a server.

Online application forms for jobs, universities and government services often ask for a scanned signature. A clean PNG looks more professional on a PDF contract, a letter or an invoice. After cleaning, you can add the signature to a PDF or bring the file down to the KB size a form asks for.
