Guide: Sign PDF

Open a PDF, create your signature, put it where it belongs and download the signed file. It is free and unlimited, with no sign-up and no watermark.

Create a signature

  • Draw it with your finger, a pen or a mouse.
  • Type your name and pick a handwriting style.
  • Upload a photo of your signature on white paper. The white background can be made transparent.

Choose black, blue or red ink. The signature is trimmed automatically and added to the current page.

Place it

Drag the signature to move it, drag the round corner to resize, or use the arrow keys, plus and minus. Use the page buttons to go to any page, and the zoom buttons for precision. Add today's date or any text with the buttons above the page.

Save

Press Apply and save PDF. Your items are stamped into the page, so they cannot be moved afterwards, and pages that were rotated in the original are handled correctly. You can also flatten form fields so typed-in values become permanent.

Good to know

  • Your files are processed inside your browser tab and are not uploaded.
  • This places a picture of your signature. It is not a cryptographic digital signature.
  • Password-protected PDFs must be unlocked first.

FAQ

Is this a legally binding signature?

It places an image of your signature on the page, like signing a printout. Whether that is accepted depends on the document and your country. It is not a certificate-based digital signature.

Can I sign on my phone?

Yes. Draw with your finger, then drag and resize the signature on the page with touch.

Is there a limit or a watermark?

No limit, no watermark, no sign-up. You can sign as many documents as you like.

Is my signature or PDF uploaded?

No. Everything stays in this browser tab. The signature is not stored anywhere once you close the page.

Can I sign several pages?

Yes. Move to any page and add the signature again, or tap the saved signature to place it on the current page.
