How to Add a Watermark to a PDF Online

Drafts leak. Watermark PDF stamps text or an image across a page range so reviewers can tell a Sample, Confidential, or Do Not Copy file from a final.

Watermarking is for repeating stamps. For a one-off note in a specific spot, use Add text instead.

Where watermarks actually get used

Label a contract draft before client review. Brand a sample brochure with a logo mark. Mark exam practice packs so they're not confused with finals. Add a version or date band across a long report.

The stamp should be visible enough to deter casual forwarding but not so heavy it hides the content underneath.

Adding a watermark

1. Open Watermark PDF.
2. Select the PDF from your device.
3. Choose text or image watermark options and the page range.
4. Apply and download.
5. Check a middle page — not only page one — so opacity and placement look right.

If pages are out of order, fix them with Organize before watermarking so the stamp lands on the pages you intend.

Because Watermark PDF stamps locally in your browser, you can mark a confidential draft without uploading it to a third-party site first.
