Frequently asked questions
How do I sign a PDF online?
Choose your PDF, tap Signature, then tap where you want to sign. Draw, type or upload your signature, tap Use signature, then save the PDF.
Can I draw my signature with my finger?
Yes. On a phone or tablet, choose Draw and sign with your finger or a stylus. On a computer, use the mouse or touchpad.
Can I use a photo of my handwritten signature?
Yes. Choose Upload and pick a photo of your signature on white paper. The paper is removed automatically, so only the ink appears on the PDF.
Is my PDF or signature uploaded?
No. Everything happens in your browser. Neither the PDF nor your signature leaves your device, and nothing is saved.
Is this signature legally valid?
It adds a picture of your signature, like signing on paper, which many everyday agreements accept. It isn't a certified digital signature, so for official or regulated documents, check what the recipient requires.
Can I add the date or my name too?
Yes. Use Text to type your name, the date or your initials anywhere on the page.
