What is PDF Watermark?

PDF watermark tool overlays customizable text — such as DRAFT, CONFIDENTIAL, or your company name — across every page of a PDF document. Users can control the watermark's position, opacity, font size, and diagonal angle to match their branding or compliance needs. Document controllers, legal teams, and content creators rely on text watermarking to label document status and deter unauthorized redistribution.

Why use PDF Watermark?

Applying a consistent watermark to every page at once eliminates the tedious manual process of editing each page individually in a PDF editor. Customizable opacity means you can make the watermark clearly visible for draft documents or subtle enough not to obscure printed content. All processing happens locally in the browser, so sensitive contracts and internal documents remain private.

How it works

A law firm stamps CONFIDENTIAL at 30% opacity across a brief before sharing it with a client for review. A design agency adds a DRAFT watermark with a timestamp to proofs sent to clients for approval. A publisher watermarks review copies of a manuscript with a reviewer's name to trace any unauthorized leaks.

Pro Tip

Setting opacity between 20–35% strikes the best balance — visible enough to serve its purpose but light enough that underlying text remains fully readable when printed. Use all-caps short text like DRAFT or SAMPLE for maximum legibility at smaller font sizes on dense document pages.

Frequently Asked Questions

Yes. You can set the watermark text, font size, opacity level, position on the page (center, top, bottom, corners), and diagonal angle. This gives you enough flexibility to create visible draft stamps or subtle branding overlays depending on your use case.
