Images are processed on our servers only during encoding/decoding operations. We do not permanently store your images or the metadata you embed. Your privacy is important to us.
The maximum metadata length depends on the image dimensions. Larger images can store more data. For most practical purposes, you can embed identification strings, usernames, dates, and short messages.
Yes, the basic watermarking and detection features are free. We believe everyone should have access to tools that protect their digital content.
Digital watermarking is a technique used to embed information into digital media such as images, audio, or video. Unlike visible watermarks (like logos overlaid on images), invisible watermarks are hidden within the media's data structure and cannot be seen or heard by users.
This technology has been used since the 1990s and continues to evolve. It serves various purposes including copyright protection, content authentication, broadcast monitoring, and leak detection. As digital content becomes increasingly easy to copy and share, watermarking provides a crucial layer of protection for content creators and organizations.
Content Lookout brings professional-grade watermarking technology to everyone through an easy-to-use web interface. No software installation required—simply upload your image, add your metadata, and download the protected version.
