About Add watermark
Add Watermark stamps text such as CONFIDENTIAL, DRAFT or your own wording across every page. Control the placement, opacity and font size.
A watermark marks a document's status or ownership without hiding the content underneath.
When to use Add watermark
- Mark a document as DRAFT or CONFIDENTIAL before sharing.
- Put your name or company on a document you send out.
- Make it clear that a copy is not the final version.
Tips for the best result
- Keep the opacity low enough that the page stays easy to read.
- Leave the font size empty to let the size fit the page automatically.
- A watermark is a visual mark, not protection: it does not stop people copying the text.
