Photo Colorizer is a web-based tool for colorizing and restoring monochrome images. Users can upload PNG, JPG, or WEBP files up to 200MB by clicking or dragging them into the workspace. The service automatically adds plausible colors while restoring scratches, tears, stains, mold, folds, and missing areas. It supports old family photographs, historical records, black-and-white illustrations, and comics. Users can select an available style, compare standard and high-quality output, and download the processed image. Free usage includes two restoration attempts each month. Paid plans provide monthly credits, output up to 3000px, faster processing, batch processing, all AI features, single processing, and ad-free use. Processing consumes credits, with standard output using one credit and high quality using two.
