A watermark marks a document's status or ownership — ‘Confidential’, ‘Draft’, ‘Sample’, or a company name — across every page. It deters unauthorised reuse and makes a document's purpose unmistakable at a glance.
Type your watermark text, choose its opacity, and the tool overlays it diagonally across each page. The watermarked file is generated locally, so your document never leaves your device.

Frequently asked questions
Can the watermark be removed later?
The watermark is drawn into the page content, so it is not a simple toggle to remove. Keep your original file if you need an unmarked copy.
Can I add an image or logo watermark?
This build supports text watermarks. Image/logo watermarks are on the roadmap for an upcoming release.
Is my document uploaded?
No. Watermarking runs entirely in your browser and the file is never sent anywhere.
