Sign PDF — FAQ

How do I sign a PDF?

Upload your PDF, draw or type your signature, choose the page, position and size, then click Sign & download. You get a new file named …-signed.pdf.

Is my file uploaded anywhere?

No. The whole thing runs in your browser — the page is rendered and your signature is stamped onto the PDF locally. Your file never leaves your device and nothing is sent to a server.

Can I draw my signature, or do I have to type it?

Either works. Draw with your mouse or finger on the pad, or switch to Type to render your name in a script font. Hit Clear to redo a drawn signature.

Is there a file size limit, and does it cost anything?

It's free with no sign-up. There's no fixed size cap, but because everything is processed in memory, very large PDFs depend on your device's RAM — a huge file may be slow on an older phone or laptop.

Where does the signature actually go, and any gotchas?

It's placed by one of nine anchor positions (corners, edges, center) and scaled by the size slider — you can't drag it to an exact pixel. It's stamped on one page at a time, so repeat for each page you need to sign. Encrypted/password-protected PDFs need to be unlocked first.

Does this count as a legal e-signature?

The signature is stamped onto the page as an image, not a certificate-based digital signature. Typed and drawn e-signatures are accepted for many everyday documents, but check the specific requirements for your use case.
