Sign PDF Online

Printing a document just to sign it, scanning it and emailing it back is slow and wastes paper. With this tool you can sign a PDF directly on your computer or phone. Draw your signature with a mouse, trackpad or finger, or type your name and we render it in a handwriting-style font. Choose the page, click the exact spot where the signature belongs — usually a signature line near the bottom — and use the size slider until it fits naturally.

The signature is stamped onto the page as an image, so it looks the same in every PDF reader and prints cleanly. The rest of the document stays untouched: text remains selectable and images keep their quality. Everything happens locally in your browser, so contracts, leases and forms never leave your device, and there's no account, watermark or limit on how many documents you sign.

Be aware of what this kind of signature is. It is a simple electronic signature, which is fine for many everyday uses such as permission slips, internal approvals, rental forms and many business agreements. It is not a certified or qualified digital signature: it contains no cryptographic certificate proving who signed or detecting later changes. If a court, bank or government office requires a qualified or certificate-based signature, use a dedicated signing service for that document.
