Stamp a text or image watermark across every page of your PDF. Control the opacity, angle, and position to make it subtle or prominent.

Common uses include marking drafts as "DRAFT" or "CONFIDENTIAL," branding documents with your company logo, or deterring unauthorized sharing. The watermark is baked into the PDF so it shows up on screen and in print.
