Sign PDF
betaThis free Sign PDF tool lets you add a signature to a PDF without printing or scanning. Draw your signature with the mouse or touch, or upload a PNG, then drag it onto the page, size it, and place it on one or more pages. Everything happens in your browser, so your document is never uploaded.

Frequently asked questions
Is my document uploaded to a server?
No. The PDF and your signature stay in your browser — signing happens locally and nothing is uploaded, which matters for confidential documents.
Can I sign more than one page?
Yes. Position the signature and add it to each page you need; all placements are applied when you download.
Can I upload an existing signature image?
Yes. Upload a PNG (ideally with a transparent background) instead of drawing, and place it the same way.
Is a drawn signature legally binding?
A drawn or image signature is a simple electronic signature. Whether it is legally sufficient depends on your jurisdiction and the document; check local requirements for important agreements.
