Why Watermark Your PDFs?

Watermarking your PDF documents provides several important benefits:

  • Protect confidential or sensitive information
  • Indicate document status (e.g., "Draft," "Confidential," "For Review")
  • Prevent unauthorized distribution of your documents
  • Add branding to reports, presentations, and other business documents
  • Maintain copyright protection for published materials
