Sign PDF Online — Draw, Type or Upload Your Signature, Free
Sign a PDF without printing, scanning or installing anything — draw your signature with a mouse, finger or trackpad, type it in a cursive font, or upload an image of one, then place it anywhere on any page. Add as many signatures as the document needs.
Beyond the signature itself, turn on an audit trail to record the signer's name, timestamp and a SHA-256 fingerprint of the original file, append a certificate of completion, or embed an actual cryptographic digital signature into the PDF for tamper-evidence — each is optional, so a quick signature stays quick.
Signing runs the same on a phone as a laptop — the drawing canvas takes touch input directly. No sign-up is required, and both the uploaded PDF and the signed result are deleted automatically after an hour. Contracts and letters up to 50 MB can be signed here.

Frequently asked questions
How do I sign a PDF without printing and scanning it?
Upload the PDF, draw, type or upload your signature, then drag it onto the page where it belongs — download the signed file straight away, no printer or scanner involved.
What's the difference between an electronic signature and a digital signature?
An electronic signature is simply your mark — drawn, typed or uploaded — showing you agreed to the document; a digital signature is a cryptographic technique that proves a file hasn't been altered since signing. Dudle's eSign tool gives you the electronic signature by default, plus an optional embedded digital signature and a SHA-256 audit trail if you need stronger tamper-evidence.
Is an electronic signature legally binding?
In most jurisdictions — including under the US ESIGN Act and EU eIDAS — a basic electronic signature is legally binding for most everyday contracts. Rules vary by jurisdiction and document type though, so check local requirements for high-value, regulated or government paperwork; this isn't legal advice.
Can I sign a PDF for free without creating an account?
Yes — eSign PDF works with no sign-up and no account. Upload, sign, and download; the file is deleted automatically after an hour.
Can I password-protect a PDF after I've signed it?
Yes — sign it here first, then run the signed PDF through Dudle's Protect tool to add a password and encryption on top, keeping the signature intact underneath.
