Why Add Watermarks?

  • Copyright protection: Deter unauthorized use of your photos
  • Brand promotion: Add your logo or website URL to shared images
  • Draft/proof marking: Label images as "Draft", "Proof", or "Confidential"
  • Attribution: Credit the photographer automatically when images are shared

Text vs Image Watermarks

  • Text watermark: Your name, website URL, copyright notice. Simple and fast to add.
  • Image/logo watermark: Your logo or brand mark. More professional but requires a logo file (PNG with transparent background works best).

Watermark Best Practices

  • Use 30-50% opacity — visible but not distracting
  • Position in a corner or diagonally across the center
  • Make it large enough to be difficult to crop out
  • White or black text works on most backgrounds
