Add a Watermark to Protect or Label Your PDF

Watermarks mark documents as confidential, copyrighted, or just branded. This tool adds text or image watermarks to your PDF pages, with controls for position, size, color, opacity, and rotation.

You can watermark every page or a selected range, and preview the result before finalizing.

Text and image options

Add a text watermark ("Draft", "Confidential", your name) with full styling control, or place an image watermark such as a logo.

Placement control

Position the watermark center, corner, or at a custom spot, and rotate it for a diagonal mark. Opacity keeps content readable underneath.
