Add a custom text watermark to PDF pages

Use a visible watermark such as DRAFT, SAMPLE, CONFIDENTIAL, or another short label to mark document status or ownership.

Apply a consistent watermark across pages

Use one watermark style across every page so the document carries a recognizable visible label.

Adjust watermark visibility

Choose Helvetica Bold, Times Bold, or Courier Bold, then adjust size, color, opacity, rotation, and one of nine positions.

Treat a watermark as a notice, not protection

A visible watermark communicates status or ownership but does not encrypt the PDF or prevent copying, editing, screenshots, or reuse.

About this tool

Place a visible text watermark across PDF pages

Watermark PDF adds text over the visible page content using the controls supported by the tool. It does not automatically provide access control or document encryption.

Useful for

  • Mark drafts, samples, review copies, or confidential copies with a visible label.
  • Add a consistent ownership or review notice across multiple pages.
  • Choose a subtle or prominent visible treatment according to the document's purpose.

Good to know

  • The tool supports text watermarks only, not image or logo watermarks.
  • Watermarking is not the same as protecting or encrypting a document.
  • Review both light and dark page areas to keep the watermark readable.
