About Add Watermark
Protect your documents and assert ownership by adding text watermarks to every page of your PDF. PDFNinja's watermark tool lets you customize the text, font size, opacity, and rotation angle to create professional-looking watermarks.
Common uses include marking documents as 'DRAFT', 'CONFIDENTIAL', or adding company names. The watermark is embedded directly into the PDF, so it appears when printed or viewed digitally.
