About this tool
Reuse your signature
Saved signatures are stored only in this browser, so you don't redraw them every time. You can delete them at any time.
An electronic signature, not a digital certificate
This adds an image of your signature to the page. It does not add a cryptographic (certificate-based) digital signature.

Can I remove the white background of a photographed signature?
