TrueColorizer is a web service that adds estimated color to existing photographs while aiming to retain the people, objects, composition, and photographic detail. It offers Hybrid, Natural DDColor, Artistic DeOldify, and Stable DeOldify methods; Hybrid is described as a 60/40 blend of DeOldify Artistic and DDColor. Users can adjust quality and color strength, compare the source and result, preview finishes, and download a full-resolution image. Uploads may be JPG, PNG, WEBP, or TIFF, up to 10 MB, and processing happens in the cloud. A free account or sign-in is required. The free plan includes three lifetime colorizations. Starter costs $4.99 per month for 50, Standard costs $7.99 per month for 100, and Pro costs $14.99 per month for 250. Subscriptions renew monthly and can be canceled from My Account. The site says photos are encrypted in transit and temporary processing files are removed after colorization; it says originals are not intentionally retained. Color choices are estimates, not proof of historical colors.
