What is Signature Generator?
Digital signatures are needed for documents, emails, contracts, and forms in the increasingly paperless workplace.

No plugins, no accounts, and your signature image never touches any server.

- 2Use the pen size slider to adjust stroke width, and pick a pen color (black, blue, or custom)
- 3Click Clear to start over, or Undo to remove the last stroke
- 4Click Download PNG to save your signature with a transparent background, ready to overlay on documents
Frequently asked questions
Is my signature stored or transmitted anywhere?
No. Your signature is drawn entirely on an HTML5 canvas in your browser. It is never uploaded, stored, or transmitted to any server. The downloaded image exists only on your device.
Can I use the downloaded signature on PDF documents?
Yes. Download as a transparent PNG and insert it into PDF editors like Adobe Acrobat, Preview (Mac), or online PDF tools. The transparent background allows it to overlay cleanly on white document pages.
Is a drawn digital signature legally binding?
In many jurisdictions, electronic signatures are legally binding under laws like the US ESIGN Act and EU eIDAS regulation. However, for high-value legal documents, use a certified e-signature service that provides an audit trail.
