Sign a PDF

Your signature is drawn on this device and merged straight into the PDF. Nothing goes to a server.

Files are processed in your browser and never uploaded
Only sign with your own signature. Copying or adding someone else's signature without permission can be forgery. This places an image of your handwritten signature — it is not a certificate-based digital signature. For contracts where legal validity matters, confirm the other party accepts this kind of signature.

No printing, no scanning

When a contract, consent form or confirmation arrives as a PDF and needs your signature, skip the print–sign–scan routine and sign it right here. The signature is laid on top of the original page as an image, so the original text and tables stay exactly as they were.

How to use it

  1. Drop the PDF to see the first page. Use ◀ ▶ to go to the page you need to sign.
  2. Sign in the “Draw” box with your finger or mouse, or use “Upload image” with a photo of your signature on paper — the white background is removed automatically.
  3. Click “Place signature on this page”, drag it onto the signature line and resize it with the circle at the bottom right.
  4. “Place date” adds today's date (e.g. Nov 9, 2026).
  5. Repeat on any other pages, then click “Download signed PDF”.

How this differs from a digital signature

This tool adds an image of your handwritten signature. It doesn't identify the signer or detect later changes the way certificate-based digital signatures do. Use it for everyday documents and for contracts where the other party accepts image signatures. Your signature and PDF are never uploaded.

Signing several pages

For documents that need a signature or initials on every page, move through the pages with ◀ ▶ and place the signature again. The list below shows which pages are signed, so you won't miss one.

Frequently asked questions

My signature is too thick or too thin.

Change the pen width and draw again. After placing, you can only change its size.

Can I add a company stamp?

Yes — upload a PNG of your own stamp using “Upload image”.

Can I move the signature after placing it?

Yes, any time before you download. In the downloaded PDF, the signature becomes part of the page.
