What is Image Watermarking?
Image watermarking overlays custom text, copyright notices, or brand logos onto photos. It serves as a vital safeguard to protect intellectual property, prevent unauthorized image theft, and maintain brand attribution across online platforms.
Our tool allows you to place text or image logo watermarks anywhere on your canvas, adjust transparency/opacity, rotate watermarks, or tile them diagonally across the entire image grid for maximum copyright protection.
All watermarking takes place locally in browser memory, ensuring your original high-resolution master photos remain safe from server interception.
