How Does It Work?

The PDF Watermark Tool uses advanced browser-based technology to process your documents directly on your device.

Upload and Processing

When you upload a PDF document, the tool processes each page individually while maintaining the original document structure and quality. The system analyzes page dimensions, content layout, and existing elements to determine optimal watermark placement.

Watermark Application

Using advanced rendering techniques, the tool applies your customized watermark to each page of your document. The watermark is embedded as a separate layer that overlays your content without altering the original text and images beneath it.

  • Text formatting and layout
