About this tool
Add Watermark
Add a custom text watermark to every page of a PDF, with control over color, angle, opacity, and position.
A visible watermark is a fast way to signal a document's status before it's final, or to discourage a shared copy from being passed off as something else. This tool stamps custom text across every page of a PDF, with control over the watermark's color, rotation angle, opacity, and position, and shows a live preview before you export.

For users who mainly need marking drafts, confidential documents, or samples before sharing, this focused approach often gives better execution speed and cleaner day-to-day usability, while still producing the PDF with a text watermark stamped on every page that is suitable for practical work.
