About Add Watermark
Add Watermark places a line of text such as CONFIDENTIAL, DRAFT or SAMPLE across your PDF pages. Set the text, font size, colour and opacity, choose the angle (diagonal, horizontal, vertical), and pick a single centered mark or a repeated tiled pattern. You can apply it to all pages or only a range.
Use it as a PDF watermark maker for drafts and confidential files: watermark PDF pages with your own wording, or stamp PDF pages with a label your colleagues can’t miss.
The watermark is drawn on top of the page content with adjustable transparency, and it is positioned correctly on rotated pages. Text is limited to Latin letters, numbers and common punctuation.
Tips
- Light gray at 20–30% opacity is easy to see without hurting readability.
- A watermark is a visual label, not a security feature; it can be removed by someone determined.
- See our best-practice guide for more.
Common uses
Mark a contract as DRAFT while it is still being negotiated, label internal reports CONFIDENTIAL, stamp previews of paid material SAMPLE, or add your company name across a proposal. A tiled watermark is a good way to share a preview while making it clear that the full version is separate.
