PDF Sign lets you draw a signature with your mouse or finger on a canvas and stamps it into the bottom-right corner of your PDF's last page, using the pdf-lib library entirely in your browser — your file is never uploaded to a server. You can only draw a signature, not type or upload an image of one, and it isn't a cryptographic digital signature — just an image placed on the page.
Is PDF Sign free to use?
Yes, it's completely free with no signup required.
Can I type my signature or upload an image instead of drawing it?
No — this tool only supports drawing a signature by hand with your mouse or touchscreen.
Can I choose where on the page, or which page, the signature goes?
No — the signature is always placed at a fixed position in the bottom-right corner of the document's last page.
Is this a legally binding digital signature?
No. It's a drawn image placed on the page, not a cryptographic digital signature with identity verification, so it may not satisfy requirements for legally binding e-signatures.
