Watermark PDF
Mark copies of IDs, contracts or drafts so they can't be reused elsewhere. Any language, any text.
The text is embedded as a high-resolution image so any language renders correctly. The original content is untouched.
This tool runs entirely in your browser. Nothing you add is uploaded to any server.

Tip: write the purpose
When sending a copy of an ID or bank statement, a tiled watermark like "For ACME rental application, Oct 2026" makes misuse much harder. Keep opacity around 20–35% so details stay readable.
Works in any language
The text is rendered as a high-resolution transparent image and laid over each page, so it never turns into empty boxes.
FAQ
Is my file uploaded?
No, everything runs in your browser.
Will the file get bigger?
Only slightly — one small image is shared by all pages.
Can someone remove it?
A determined person with a PDF editor could. To hide information permanently, black it out with Blur & Redact.
