PDF watermarking adds a text or image overlay to one or more pages of a PDF document. Watermarks serve as visual markers indicating ownership, confidentiality status, or document stage — such as 'DRAFT,' 'CONFIDENTIAL,' or a company logo.
Watermarks can be placed above or below the existing content, adjusted for opacity, positioned precisely on the page, and applied in a tiled pattern for full-page coverage.
Word processors and desktop PDF editors can add watermarks, but the process is often buried in settings menus and lacks visual control. Online watermarking tools upload your documents to remote servers.
This tool provides a real-time visual preview of your watermark with full position, opacity, and tiling controls. Everything is processed locally in your browser.
