Sign a PDF — draw, type, or upload

Add your signature to a PDF in three ways: draw, type, or upload an image. Place it anywhere, then download.

Files are processed entirely in your browser. Nothing is uploaded to any server.

How it works

  1. 1

    Upload PDF

    Drop the PDF you want to sign.

  2. 2

    Create signature

    Draw on the canvas, type your name in a script font, or upload a signature image.

  3. 3

    Place & download

    Drag the signature into place, resize, and download the signed PDF.
