About the Sign PDF
Draw your signature with a mouse, pen or finger, then click the page where it should go and download the signed PDF. The page is shown as you place it, so the position is what you see rather than a guess at coordinates. It works the way signing a printout and scanning it back does - the mark is drawn onto the page.
How to sign a PDF for free
- Choose the PDF.
- Draw your signature with a mouse, a trackpad, a stylus or your finger.
- Pick the page, set the signature's width, and click the page where it should go.
- Press Sign and download.
It works in the browser on Windows, Mac, iPhone and Android, with no Adobe account and no upload: the document is signed on your device. To sign several pages, sign one, then load the downloaded file and sign the next.
Is this a legal electronic signature?
It is a drawn signature placed on the page - the electronic version of signing a printout and scanning it back. Many everyday documents accept that: a tenancy form, a permission slip, a freelance contract. It is not a certificate-based digital signature, which proves who signed and that the document has not changed since. Some documents - certain government, banking or court filings - require that kind. If in doubt, ask whoever asked you to sign which they accept.
Tips for a clean signature
- Sign larger than you need and shrink it with the width slider - small drawings look shaky.
- A stylus or finger on a phone usually gives a more natural signature than a mouse.
- Combine the signed pages with other documents using Merge PDF, or turn a photo of a signed paper page into a PDF with JPG to PDF.
- Sending it on? Add a password with Protect PDF, and remove anything private first with Redact PDF.
