How It Works
Upload a PDF, draw your signature on the canvas pad, then position it on any page. The canvas signature is converted to a PNG and embedded into the PDF using pdf-lib.js — no server interaction.
Adjust the signature size, horizontal position, and vertical position using slider controls. Choose which page to place it on, then download the signed PDF instantly.
