Thanks for the feedback!
Add a semi-transparent diagonal text watermark — "CONFIDENTIAL", "DRAFT", your name or company — across every page of a PDF. It runs entirely in your browser, so sensitive documents are never uploaded anywhere.
How to use it
Upload your PDF, type your watermark text, and click Add watermark. The text is drawn at 45° with low opacity so the page stays readable. Want page numbers too? Use Add Page Numbers afterwards.
