Palette.fm

Palette.fm is an AI photo colorization service that turns black-and-white images into full-color photographs. Users upload a photo, pick from more than 21 color filters, and can further adjust the result by typing color keywords for specific objects in the scene. The service is made by Palette FM, Unipessoal LDA, a company based in Porto, Portugal, and reports more than 6.6 million users and 54 million photos colorized to date. A free plan includes one full-resolution, watermark-free credit plus unlimited watermarked previews capped at 500x500 pixels. Paid options include a $72 per year subscription with 480 credits and up to 10x faster processing, or a one-time $49 purchase for 75 credits valid for two years. Output resolution can reach up to 5000x5000 pixels on paid plans, and pro users can pin and organize favorite filters. An API is available for developers who want to integrate colorization into their own products. Palette.fm focuses narrowly on colorization rather than broader photo editing, so it does not offer retouching, upscaling, or other restoration features beyond adding color and light stylistic adjustments through its filters and keyword system.
