Tips

  • Use diagonal angles (30-45 deg) to deter cropping
  • Preview tile density before downloading the result

Fun Facts

  • Digital watermarking dates to 1993 when Andrew Tirkel and Charles Osborne published the first algorithms for embedding imperceptible marks in images.
  • The term 'watermark' originates from 13th-century Italian papermakers who used wire molds to impress translucent marks into wet paper pulp.
  • Digimarc, founded in 1995, was the first company to offer commercial invisible watermarking and now tracks billions of media assets worldwide.

FAQ

Text or image watermark?
Text only in this tool. For logo watermarks, use the Image Editor and manually place the logo as a layer.
Does it tile?
Yes — toggle 'tile across image' to repeat the watermark pattern. Good for copyright protection; single-watermark for subtle branding.
Opacity and angle control?
Both — opacity 10-100%, angle 0-360°. Subtle watermarks use 20-30% opacity + 45° angle.
Can I remove a watermark?
No — there's no automated way to remove watermarks from an image. Some ML tools attempt it with variable quality; none are 100% reliable.
