What is Kolorize?
Kolorize is a web-based AI tool that automatically adds color to black-and-white photographs and restores color in faded, vintage, or sepia-toned images. Users upload a photo, preview multiple colorized variations for free, and pay one credit per full-resolution download. It also colorizes video frames (1 credit per 100 frames) and preserves the original grain, focus, and resolution. Files are processed over an encrypted connection and deleted automatically after processing.
