Colorize This

Colorize This is a web-based AI tool from Bluusun Venture Studio that turns black-and-white photographs into color images. Users upload a photo in JPEG, PNG, or WebP format (up to 4MB), and the service applies AI image models, including Flux, to generate several colorized variations of the same picture, from which the user can pick the best result. An optional text prompt can be added to steer the colorization toward a specific look. The free tier produces one colorized image per day, capped at roughly 512 pixels and marked with a watermark, enough to try the tool but not for serious use. The Pro tier removes the watermark, unlocks higher-resolution output up to 8K, allows batch processing of multiple photos, and includes a commercial license for print or business use. Colorize This states that uploaded images are processed on its own infrastructure and deleted within 48 hours, and that it does not share data with third parties or use it to train its models. The tool is aimed at people restoring old family photographs as well as photographers and small businesses that need higher-resolution, licensed colorization. One limitation is that the free tier's low resolution and watermark make it mostly a preview rather than a finished result.
