Watermark PDF stamps a custom text watermark — like "Draft", "Confidential", or your company name — across every page of a PDF document. You control the text, opacity, rotation angle, and position so the watermark is visible without obscuring the underlying content. It's commonly used to mark draft contracts, protect shared proposals from unauthorized redistribution, or brand documents before sending them externally. The watermark is embedded directly into the PDF locally in your browser, with no file ever leaving your device.
