What is a PDF watermark for?
A watermark is text printed lightly across a page. It tells readers what a document is and who it belongs to. Common examples are DRAFT on documents still being reviewed, CONFIDENTIAL on private reports, COPY on scanned certificates, and your name or company on work you share.
Good settings to start with
| Purpose | Position | Opacity | Angle |
|---|---|---|---|
| DRAFT or CONFIDENTIAL | Centre | 20–30% | 45° |
| Protecting a copy of an ID or certificate | Tile across page | 15–25% | 30–45° |
| Name or website as credit | Bottom centre | 40–60% | 0° |
Protect copies of your ID documents
When you send a copy of your CNIC, passport or degree to a company, add a watermark such as “For XYZ job application only – 2026” across the page. If the copy is misused elsewhere, the watermark shows it wasn't meant for that purpose. A tiled watermark is much harder to edit out than one in a corner.
Any language works
The watermark text is drawn by your browser, so Urdu, Arabic, Hindi and emoji display correctly, not just English letters.
Keep the original
The watermark becomes part of each page, so keep an unwatermarked copy. For pictures instead of PDFs, use the Image Watermark tool.
