    How it works

    1. Add your PDF

      One or more files.

    2. Choose a stamp

      Pick a word or type your own, then set colour, place and angle.

    3. Download

      Check the preview and save.

    Clear status marks

    A stamp shows the status of a document at a glance. Choose a ready-made word or type your own, and place it on all pages or only some.

    Private

    Your file is processed inside your browser with the open-source pdf-lib library. It is never uploaded, and nothing is saved after you close the page.

    Questions

    Are my files uploaded?

    No. The tool runs inside your browser, so your files are opened and changed on your own device. They are never sent to us or to anyone else.

    Can the stamp be removed later?

    The stamp is drawn on the page. It can be edited with full PDF editors, so it is a mark, not a security feature.

    Is it free?

    Yes. Free to use, with no sign-up, no watermark and no daily limits.
