How it works

Drop or select a PDF — a page preview renders locally in your browser.
Draw a signature, import a PNG or JPG image, or reuse one saved in this browser.
Click or drag on the page to position the signature, adjust its size, then download the signed PDF.

Your files never leave this page

Every conversion runs entirely in your browser using WebAssembly. There is no upload, no server-side processing, no analytics, and no cookies. Open DevTools → Network during the operation and you will see zero outbound traffic.
