PDFs are made to travel — quotes to clients, contracts to counterparties, drafts to reviewers, portfolios to prospects. A watermark tells every reader, on every page, exactly what the document's status is. It's five minutes of work that makes forwarded copies self-identifying.
Choosing the right stamp text
- DRAFT — early versions that shouldn't be treated as final. Stops "I thought this was done" chaos.
- CONFIDENTIAL — internal numbers, legal drafts, HR material. Signals handling expectations.
- PREVIEW / SAMPLE — deliverables shown before payment (designs, photos, reports).
- © Name, Year — copyright claim on portfolios, ebooks, spec sheets.
- DO NOT COPY / NOT FOR DISTRIBUTION — explicit restrictions for training materials and paid documents.
The classic look (and why it works)
Diagonal (45°), centered, large but transparent — around 35% opacity in red for CONFIDENTIAL, or gray for DRAFT. The diagonal orientation crosses both reading axes so it can't be ignored, while the transparency keeps the text underneath readable. Size it to about a quarter to a third of the page width.
How to do it (free, no upload)
- Open the watermark PDF tool.
- Type your stamp text, set ~6% size, red or gray, 35% opacity, 45° rotation, center position.
- Drop your PDF — the stamped version is generated and downloaded instantly, every page marked.
Because the tool runs entirely in your browser, confidential documents stay confidential — nothing is uploaded to anyone's server.
Common questions
Does the watermark go on every page?
Yes — a watermark on page 1 only invites page-2 screenshots. Always stamp the whole document.
Can watermarks be removed?
Text stamps are technically removable with PDF editors by determined users. The purpose is deterrence and self-identification of copies, not encryption — for real secrecy, use password protection instead of (or alongside) a watermark.
Images too?
Yes — use the watermark photo tool or batch mode for images inside or outside documents.
