A diagonal CONFIDENTIAL stamp tells every reader how to treat a document; DRAFT stops an unfinished version being mistaken for the final one; COPY or SAMPLE marks a document as not the original. The text is ready on this page — change it to any word, in any language, choose the colour and transparency, and apply it to all pages or just some.
Tips for the best result
- Red at 25–35% transparency is the classic CONFIDENTIAL look; grey works well for DRAFT.
- Tiled watermarks are harder to crop out of screenshots.
- Combine with Protect PDF to require a password to open the file.
