Page Numbers / Watermark
Add page numbers and text watermarks to a PDF in the browser, with full control over position, size, opacity, and prefix, and no upload required.
What it does
- Add page numbers with configurable position, start number, and prefix
- Stamp a text watermark with adjustable size and opacity
- Page numbers and watermark can be applied independently or together
- All annotation runs client-side, files never leave the browser
When a draft needs CONFIDENTIAL stamped on every page before it goes to reviewers, the watermarking guide explains that marking runs client-side — configure text, opacity, and position here, then export a stamped file for lawyers.
