PDF Watermark
Add a text or image watermark with custom pages, position, rotation, typography, size, and opacity.
Stamp a text or image watermark across selected pages of a PDF, with full control over position, rotation angle, font, size, and opacity. Useful for marking a document DRAFT before internal review, adding a company logo to shared reports, or discouraging unauthorized redistribution of a document you're sending externally. The watermark is applied locally with pdf-lib and layered into the page content, and can target all pages or a specific range like 1-3,5,8-10.

Common questions
Can I watermark selected pages?
Yes. Use "all" or a range such as 1-3,5,8-10.
Which image formats work?
Use a PNG for transparency or a JPEG for photographs and solid logos.
Does it upload my PDF?
No - the watermark is added entirely in your browser using pdf-lib.
Can I rotate the watermark diagonally?
Yes - set a custom rotation angle, with 45 degrees a common choice for a classic diagonal DRAFT-style watermark.
