Sign a PDF online

Draw your signature with a mouse, trackpad or touchscreen and drop it onto the signature line. The signature stays in your own browser; neither the file nor the signature is uploaded.

How it works

  1. Open the PDF Choose the file or drop the PDF onto the page.
  2. Click "Signature" Draw your signature on the pad that opens. You can change the ink color or clear it and start over.
  3. Place it on the document Click "Use" to put the signature on the current page as an image, drag it into position and drag a corner to resize.
  4. Export Click "Export PDF". The signature is drawn onto the page and you get a new file with no watermark.

Good to know

  • Your signature is remembered in this browser (never uploaded) so you can reuse it next time; clearing site data means signing again.
  • This places a handwritten image on the page. It is not a certificate-based digital signature and has no tamper-evident verification.
  • Need several signatures in one file? Copy a placed signature and drag the copy to the next spot.

FAQ

Is my signature uploaded or stored on a server?

No. It is kept in your own browser's local storage, and editing and exporting happen on your device.

Is a signature made this way legally binding?

That depends on the situation and the other party's requirements. This only places a handwritten signature on the PDF; it is not a certificate-based e-signature, so use a certified e-signature service where one is required.
