How to sign a PDF on your phone
A contract lands in your inbox and the sender wants it back signed — but you are nowhere near a printer. Your phone's browser is enough: draw your signature once, place it on the page, and send the signed copy back in minutes.

The whole job in four minutes
Add the PDF to the signing tool below, draw your signature with a finger, then drag it onto the right spot on the page. You can resize it to fit the signature line and add the date the same way. Because it all happens in the browser on your phone, the document is never uploaded anywhere.
Signatures that look right
- Sign slowly — rushed finger signatures look shakier than they need to.
- Use landscape orientation for a bigger drawing area.
- Size the signature to the line: oversized signatures look pasted-on, tiny ones look accidental.
- Check the colour matches the document — black or dark blue reads as professional.
Is a drawn signature valid?
For most everyday documents — leases, offer letters, consent forms, freelance contracts — a drawn electronic signature is legally accepted in the US, UK, EU and most other jurisdictions. Certain documents (wills, some property transfers, notarised filings) still require wet ink or a specific e-signature service, so check the instructions if the document is one of those.

Frequently asked questions
- Can I reuse my signature?
- Yes — draw it once and it stays available while you work through the document, so multi-page contracts take seconds per page.
- Does it work on both iPhone and Android?
- Yes, in Safari, Chrome or any modern mobile browser — no app to install on either.
