About the Watermark PDF Tool

This tool stamps a text watermark, such as Confidential, Draft or Copy, across the pages of a PDF. A watermark discourages misuse, marks the status of a document, or labels it with your name or company. You can usually control the text, its angle, size and how faint it appears, so it is visible without hiding the content underneath.

How to add a watermark to a PDF

  1. Open the PDF you want to mark.
  2. Type the watermark text you need.
  3. Adjust the size, angle and transparency.
  4. Preview how it looks across the pages.
  5. Download the watermarked PDF.

This is handy for marking a draft contract, labelling shared copies of a report, or stamping your name across documents before sending them out. The watermarking runs entirely in your web browser, so your file is never uploaded to any server and your document stays private on your own device.

Can I control the look of the watermark?

Yes, you can usually set the text, size, angle and transparency. This lets you make the watermark clearly visible without obscuring the content.

Will the watermark appear on every page?
