Sign PDF

Places a drawn or typed signature or a seal image anywhere on a PDF, adds text such as a date or name, and saves the result. Use it to sign a contract or form and send it back without printing.

How to use

1. Drop the PDF to sign onto the page or click to choose it. A sample document is open to start with.
2. Under "Make a signature", create one with "Draw", "Type" or "Upload image", then press "Use this signature".
3. Drag the signature into place and resize it with the corner handle. Add "Today's date" or "Name" under "Add text" if needed.
4. If the same signature is needed on every page, press "Put on every page". When you are done, press "Save signed PDF".

How it works

• This tool only places a visible signature picture on the document. It is not a certified or cryptographic electronic signature: it does not prove who signed and does not protect the file against changes.
• For a photo of a seal or a paper signature, turn on "Make a white background transparent" so only the ink remains.
• Everything is processed on this device. Signatures stay in the browser only when "Keep my signatures on this device" is on; turn it off on a shared computer.

Questions and answers

How do I add my signature to a PDF?

Open the PDF, sign with your finger or mouse under "Draw" and press "Use this signature". Drag it onto the signature line and press "Save signed PDF".

Can I add a stamp or seal to a PDF?

Yes. Add the seal picture with "Upload image". A photo of a seal stamped on white paper, or a PNG with a transparent background, works well.

Is a signature added this way legally valid?

The tool only adds a picture; it does not verify the signer or protect the file. Ask the receiver which kinds of signature they accept.

Can I put the same signature on every page?

Yes. Place the signature on one page, select it and press "Put on every page"; it is added at the same spot on the other pages.
