About PDF signature
Type your name, draw a signature, or upload a signature image, then stamp it onto the pages you choose. Everything runs in your browser and downloads a new PDF.
How it works
Dockzio flattens your signature onto the page content with pdf-lib — as text drawn with a script-style font, or as an embedded image.
Type, draw, or upload
Type a name for a quick stamp, draw with your mouse or touchscreen, or upload a PNG, JPG, or WebP of your signature.
Not a digital signature
This creates a visual signature mark, not a cryptographically verified e-signature. It does not authenticate identity or meet legal e-signature standards on its own.
Privacy first
Everything is processed locally in your browser. Your documents and signature are never sent to a Dockzio server.
