Kolorize vs AI Image Upscaler on AI Image Enlarger

Kolorize is an online photo colorizer that turns black-and-white and vintage images into full-color restorations using proprietary AI models. Upload a photo up to 4096×4096, preview unlimited variations for free, and pay only when you download a result you want to keep.

The service handles family portraits, historical archives, and sepia or yellowed vintage prints. Processing typically takes three to eight seconds per image, with grain and resolution preserved rather than painted over.

Kolorize also offers video colorization and sells credit packs instead of subscriptions. Credits last two years, cover commercial use, and are charged only on download, not preview.
