Key takeaways
- Watermark PDF stamps your chosen text across every page of a document automatically.
- Common uses: marking a document as 'Draft' or 'Confidential', or branding a report with a company name before sharing.
- The watermark is applied in one pass — no need to add it page by page.
Adding a watermark
Open Watermark PDF, drop in your file, type the watermark text, and download — it appears on every page of the document.
Frequently asked questions
Can I watermark an image instead of a PDF?
Yes, for photos and images use [Watermark Image](/watermark-image) instead.
Does the watermark stop someone from editing the PDF?
No — a watermark is visual, not a security measure. For actually locking a PDF, use [Protect PDF](/protect-pdf) to add a password.
