Add Watermark

Stamps a text or image watermark across every page of a PDF, commonly used to mark a document as a draft or confidential, or to brand it with a logo before it's shared. It's a visual signal, not a security measure -- the watermark makes the document's status or origin obvious to anyone looking at it, but doesn't prevent copying, editing, or redistribution the way password protection does.

Upload your PDF, choose Text or Image, then set the watermark content, opacity, and position (or Tiled, to repeat it across the whole page). Download the watermarked file when it looks right.
