Watermark PDF
Stamp text across every page.
Runs entirely in your browser. Verify it in your network tab.One file at a time.
What this does
Draws the text once per page, centred. It sits on top of the existing content.
Limits
- Text watermarks only. Image watermarks are not supported.
- Latin characters only. The stamp uses a built-in PDF font, which cannot draw Cyrillic, Greek, CJK or emoji.
- A watermark is not security: it can be removed by anyone with the right tool.
Is this private?
Yes, and you can check rather than take our word for it. Open your browser's network tab and run the tool: your file never appears in it, because there is no server to send it to. The whole site is static files.
