One PDF file — stamps every page diagonally
Lay a text watermark — a word like DRAFT, CONFIDENTIAL, or your name — across the pages of a PDF so anyone viewing or printing the file sees the label on every page. The text is drawn onto each page with pdf-lib in your browser, over your existing content, and a new stamped copy is produced without the file being uploaded.
Because the text becomes part of the page, it shows on both screen and printouts, and it isn't a layer you can toggle off in a viewer later. Keep your original un-watermarked file — the tool always writes to a new copy and leaves the source untouched.
Frequently asked questions
- What kind of watermark can I add?
- A text watermark — a word or short phrase such as DRAFT, SAMPLE, or CONFIDENTIAL — applied across the document's pages. It's for labelling a document's status, not for placing a full graphic overlay.
- Will the watermark show when the file is printed?
- Yes. Because the text is part of the page, it appears both on screen and on any printout — usually the whole point of watermarking.
- Is my PDF uploaded to add the watermark?
- No. The stamping is done in your browser with pdf-lib, so the document never leaves your device.
