Kolorize vs Palette.fm

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.

Palette.fm colorizes black-and-white photos through a browser upload flow with 21+ filter presets and keyword-based color tweaks. Upload an image, pick a filter, adjust descriptive keywords if needed, then download a full-resolution result or keep iterating on previews. The photo editing workflow targets family historians, photographers, and creators restoring old prints without opening Photoshop.

Most colorizers lean on heavy sepia and purple casts with little room to steer skin tones or fabric colors. Palette.fm lets you click a filter then fine-tune hues through plain-language keywords, and it sells one-time credit packs alongside subscriptions. Free previews cap at 500x500 pixels with a watermark, while paid credits remove the logo and support files up to 5000x5000 pixels.

Genealogy researchers, photo archivists, and YouTube educators use Palette.fm to batch-test color looks before committing credits. The site reports 54 million photos colorized and 6.6 million registered users, with an API option for teams that want programmatic access.
