Add Watermark to PDF Online Free

A PDF watermark is text or an image overlaid on every page of a document. Watermarks are commonly used to mark documents as "Draft," "Confidential," "Sample," or to add branding. They serve as a visual indicator of the document's status or ownership.

Our watermark tool lets you add customizable text watermarks with full control over font size, opacity, rotation angle, and color. The watermark is applied to every page of your PDF, creating a professional and consistent appearance.

All processing happens locally in your browser — your documents and watermark content remain completely private.

3. Customize appearance — Adjust font size, opacity, rotation, and color.
