Summary

Colorize Photo is a free web tool that adds color to black-and-white pictures with an on-device neural colorization network. Its Auto mode predicts colors using the ECCV 2016 “Colorful Image Colorization” model, which downloads once at about 39 MB. Users can choose from eight tonal palettes or make touch-ups with a manual brush. The tool supports batch processing without a stated photo-count limit and lets users download the batch together. It accepts JPG, PNG, WebP, and other formats the browser can open, and exports JPEG, PNG, or WebP with adjustable quality and size controls. The longest side can be up to 4096 px, and each photo has 15 undo steps. Clipboard paste and PNG copying are supported. Processing takes place in the browser using Canvas API and WebAssembly; the maker says images are not uploaded, stored, or tracked. It requires no installation or signup and has no watermark.
