When to use Watermark PDF
- Mark drafts as DRAFT or CONFIDENTIAL before circulating them.
- Stamp copies of ID documents with “Copy for XYZ only” to discourage misuse.
Tips for better results
- Low opacity (15–25%) keeps text readable while still showing the mark.
Good to know
- A watermark deters casual reuse but can be removed by someone determined.

Frequently asked questions
Does this stop people copying my PDF?
No. A watermark discourages reuse and signals status, but it isn't encryption or access control.
Can I use an image or logo?
This tool adds text watermarks. For a logo, place it as text-free artwork using our PDF Editor.
Can the watermark be removed?
It's drawn into the page content, so it can't be toggled off in a normal reader — keep your unmarked original.
Does it work on scanned PDFs?
Yes. The watermark is drawn on top of the page whether it contains text or a scanned image.
