Private by design. Add a text or image watermark across your PDF pages, with control over opacity, angle, and position. Your file is processed entirely in this browser tab using WebAssembly — it is never uploaded anywhere, so it stays yours even on a shared or offline computer.
Frequently asked questions
- Can I control how visible the watermark is?
- Yes. The opacity slider goes from faint to fully solid, so you can balance visibility against readability.
- Does the watermark appear on every page?
- Yes, it is stamped diagonally across every page of the document in one pass.
- Can I change the watermark color?
- Yes. Pick any color — a common choice is a muted gray or red to signal draft or confidential status.
