About StampAPDF

StampAPDF started with a simple everyday problem: needing to put a signature or company stamp on a PDF without installing software, creating an account, or uploading a private contract to someone else's server.

Modern browsers are powerful enough to do this work themselves — so that's how every StampAPDF tool is built. Your files are opened, edited, and saved entirely on your own device. We never see them.

The site is free to use with no page limits or trials, supported by advertising. If a tool saves you time, that's the whole point.
