Watermark PDF
Add a subtle text watermark to PDF pages. Your files are processed locally in your browser.
🔒 Files stay on your device. The processing library is loaded from a CDN and requires an internet connection. Password-protected or damaged PDFs may not work.
Add a text watermark to a PDF
Place a visible text watermark on PDF pages, for example DRAFT or CONFIDENTIAL. A visual watermark is not a security mechanism and does not prevent copying or redistribution.
How to use this tool
Choose a PDF, enter watermark text, apply it and check the downloaded file to ensure the watermark does not obscure important information.
Privacy and limitations
File processing is designed to happen in your browser. PDF tools load processing libraries from third-party CDNs; the page must connect to those providers. Keep your original files and verify the downloaded results. Very large or password-protected files may not work.
