What is the PDF Watermark Generator?
PDF Watermark Generator is an online tool that adds text watermarks to your PDF documents and lets you download a protected copy in seconds. You can tune text, color, opacity, rotation, and position while checking the preview.
No installation is required. Everything runs in your browser, and both all-page mode and custom range mode are supported for practical document-sharing workflows.

- Add CONFIDENTIAL marks to proposals and quotations

PDF Watermark Setup Tips
To keep documents readable, tune opacity and placement first. A good starting point is 20–40% opacity, and wider repeat gaps when using full-page patterns.
Recommended Starting Values
- Opacity 25–35%: Keeps text visible without blocking content
- Rotation 20°–35°: Helps avoid heavy overlap with body text
- Repeat gap 180–260pt: Practical density for most reports
Range Input Example
Use comma-separated ranges like 1-3,5,8-10. Page numbering starts from 1, and numbers above the document page count are not allowed.
Frequently Asked Questions
Are uploaded PDFs stored on your server?
No. Processing happens in your browser, and files are not uploaded or stored on our server.
Can I watermark only selected pages?
Yes. In custom range mode, enter values like 1-3,5 to apply watermark only to those pages.
What is the difference between repeat and single placement?
Single placement draws one watermark at the chosen coordinates, while repeat mode tiles watermark text across the whole page.
Will preview match the downloaded PDF?
Yes. The same render path is used for preview and export, so the output should match your settings closely.
Can password-protected PDFs be processed?
Some encrypted PDFs cannot be handled due to browser constraints. If that happens, try again with an unlocked copy.
