About Kolorize
Kolorize is an AI-powered photo colorization tool that transforms black and white photographs into full-color images. The service uses a machine learning model trained on millions of restorations to infer true, era-accurate colors rather than applying simple tints. Users upload monochrome photos and the tool analyzes tone, texture, and context to rebuild color in seconds without requiring any settings or manual adjustments. The platform is designed for family historians, photographers, archivists, and anyone looking to restore old photographs. Kolorize stands out through its privacy-first approach—files are transmitted over 2048-bit encrypted connections and deleted immediately after processing. The tool generates multiple color interpretations for each photo, allowing users to compare variations before committing to a download. A notable limitation is that the maximum image size is capped at 4096×4096 pixels, which may restrict work with extremely high-resolution originals.
