MergeImages Photo Colorizer is a free browser tool that predicts colors for black-and-white photos, scans, and archive prints. It is suited to old family photographs, scanned prints and negatives, genealogy collections, archives, and historical images. Open its page, provide an image, and download the colorized result; no account, email, browser extension, or app is needed. The tool accepts JPEG, PNG, WebP, and GIF files up to 7.5MB. You can also paste an image or provide an image URL. Processing uses DDColor on Replicate, applying predicted color at 80% strength while retaining the source image’s brightness channel. Results download as PNG files, with the longest side capped at 1024 pixels. The site says a typical colorization takes about 20 seconds, though a cold start can take up to a minute. Images travel over HTTPS to MergeImages’ servers and Replicate, and are automatically deleted within 7 days. The maker says images are not sold, shared, or used to train models. Color choices are estimates: sepia input may be interpreted differently, and the tool does not repair scratches, tears, or fading. MergeImages is built and maintained by Bello M. Amadou.
