About PDF Watermark

Protect your PDF documents with professional watermarks. SignForge's watermark tool lets you add customizable text watermarks to every page of your PDF — completely free.

Customize the watermark text, opacity (from subtle to bold), rotation angle, and font size. Common uses include marking documents as 'DRAFT', 'CONFIDENTIAL', 'SAMPLE', or adding your company name for branding.

The watermark is permanently embedded in the PDF and cannot be easily removed, making it ideal for protecting sensitive documents shared with external parties.
