How to sign a PDF for free without printing
Updated 2026-10-19
Printing a document, signing it with a pen and scanning it back is slow and makes the file blurry. An electronic signature placed directly on the PDF looks cleaner and takes a minute.
Ways to create your signature
- Draw it with a finger or stylus on a phone or tablet — the most natural look.
- Draw with a mouse or trackpad on a computer.
- Upload a photo of your signature on white paper.
- Type your name in a handwriting-style font.
Signing the document
- Open Sign PDF and add your file.
- Create your signature and place it on the signature line.
- Resize it to fit, add the date if needed, and download.
Lock it in
Run the signed file through Flatten PDF so the signature becomes part of the page and cannot be dragged off by someone else.
Is an electronic signature legally valid?
In many countries a simple electronic signature is accepted for everyday agreements, but some documents — property deeds, certain government filings — require certified digital signatures or wet ink. Check with the recipient when in doubt.
