WHAT TO KNOW

Sign PDF documents privately in your browser

Upload a PDF, create your signature and place it wherever you need it. Your document stays in your browser throughout the process. This tool adds a visible electronic signature; it does not provide certificate-based digital signing, identity verification or a formal signing audit trail.

Check the resulting file for image quality, readability, links and other important features before replacing the original.
