Add a Watermark to a PDF — Text Watermark on Every Page
Add a text watermark that runs diagonally across every page of a PDF. You set the wording and opacity, and the watermark is written into the file on save.

FAQ
Can I edit the watermark after applying it?
Yes, before you save. Open the watermark dialog again — it opens as Change watermark — and update the text or opacity.
How do I remove a watermark?
Open Tools › Remove Watermark before you save. This removes the watermark you added and any existing watermark or stamp annotations in the PDF. After saving, the watermark is part of the page and this command cannot remove it.
Can the app remove watermarks that were in the PDF before I opened it?
It removes watermark and stamp annotations. Watermarks printed directly into the page content cannot be removed this way.
