What this tool does
A watermark tells anyone who opens the file what it is and who it belongs to. PDFMaster draws your text once on every page, either across the page at 45 degrees or straight across the middle, and sets it behind the existing content so nothing becomes unreadable. Choose the wording, size, opacity and whether the page shows it diagonally or horizontally. The original text stays selectable and the images keep their quality.

Frequently asked questions
- Will the watermark cover my text?
- No. It is drawn behind the page content and defaults to 30% opacity, so body text stays readable.
- Can I watermark only some pages?
- Not yet -- the text goes on every page. Extract the pages you want first, stamp them, then merge back.
- Does it work on scanned PDFs?
- Yes. The watermark is a drawn overlay, so it does not depend on the page containing text.
- How long are my files kept?
- Files are deleted automatically two hours after upload.
