About this tool

Signing a PDF doesn't need a cryptographic signature every time — often a scanned or drawn signature stamped at the right spot is exactly what's asked for. Drawing it directly avoids the extra step of a phone photo and a separate image editor.

How to use it

  1. Draw a signature with your mouse or trackpad, or upload an image of one.
  2. Upload the PDF, then click on the page preview where the signature should go.
  3. Set its size and which page(s) it should appear on, then download the signed PDF.

Examples

Signing the last page of a contract

A drawn signature, placed at the bottom-right of page 3 of 3
The same PDF with the signature image stamped at that exact spot on page 3 only.

Common problems

The signature looks the wrong size on the page.
Width and height are set independently in millimetres — check both match the signature's actual proportions, or it will look stretched or squashed once placed.
