About Sign PDF

Sign PDF contracts, consent forms and delivery notes without printing and scanning them. Create a signature in one of three ways: draw it with a mouse, finger or stylus, type your name in one of three handwriting-style fonts, one of them a Chinese brush style, or upload a photo of your signature on paper and let the white background drop away. Choose black, blue or red ink. For a form with blanks to complete as well, Fill PDF Form lets you type, tick boxes and sign in one go.

Click on a page to drop the signature there, drag it into position and pull the corner to resize it. Place it on as many pages as you need, and add today's date or a short line of text the same way. This is a visual signature stamped onto the page, not a certificate-based digital signature, which some official filings require.

FAQ

Sign PDF: questions and answers

Can I sign PDF files with the signature I use on paper?
Yes. Take a photo or scan of it, choose Upload, and keep Remove the white background ticked so only the ink lands on the page.
How do I sign PDF documents on my phone?
Open this page and choose the PDF, tap Create signature and draw with your finger. Then tap the spot on the page where the signature belongs. When the signed file has to go back with other documents, Merge PDF combines them into one PDF.
Is this a certified digital signature?
No. It places an image of your signature on the page, the way a pen would. If a form asks for a certificate-based digital signature, you'll need a service that issues one.
How many documents can I sign for free?
Creating and placing signatures costs nothing; each signed download counts as one task. That's 2 in total without an account, 2 a day with a free one, and unlimited with VIP.
Do you keep my signature?
No. It's sent along with the document for this one task, and both are deleted from our server after an hour. We never reuse it or show it to anyone.
