What Is a PDF Watermark Tool?

A PDF watermark tool allows you to add visible text or image overlays to your PDF documents.

Tips for Effective Watermarking

  • Balance Visibility: Make watermarks visible enough to serve their purpose but not so prominent that they interfere with content readability.
  • Use Appropriate Opacity: Subtle transparency (30-50%) works well for background watermarks, while 100% opacity suits stamps and labels.
  • Consider Placement: Place watermarks in corners or margins for discrete branding, or center/diagonal for stronger protection.
  • Match Your Brand: Use brand colors and logos for professional documents that reinforce your identity.
  • Test Different Positions: Preview watermarks in various positions to find what works best for your specific document.
  • Use Clear Text: For text watermarks, use readable fonts and sufficient size for effective communication.
  • High-Quality Images: Upload high-resolution logos or images for professional-looking image watermarks.
