Molyin Photo Colorizer vs Palette

Molyin Photo Colorizer turns black-and-white prints into color PNGs while repairing scratches, creases, and fading in the same pass. The web tool accepts JPEG, PNG, and WEBP images up to 15 MB each, and processes as many as 10 photos in parallel. Each photo uses 16 credits, with no daily cap; colorization and repair are charged together, and credits for failed jobs are refunded automatically. The output is a PNG at about 1K resolution, with the image proportions preserved. New users receive 10 free credits, and free-tier creations remain stored for 7 days. Paid one-time packs start at $4.99, paid once; other listed packs range up to $1,499, paid once. Annual plans are also listed, including Pro Yearly at $2,959 a year. Storage duration varies by plan from 7 to 365 days, after which results are deleted. Molyin lists commercial use for all plans and says it does not train on uploads or publish creations without explicit consent.

Palette colorizes uploaded photos after a user chooses a filter. Its web app offers more than 21 color filters, with descriptions and keywords available to fine-tune colors. Palette supports batch processing, and says a simple script can colorize over 1 million images per day. Its API supports automated and custom prompts, reference images, and up to 120 prompts for one image. The documented image limit is 4K resolution and 10MB per file. A beta Video API handles video-frame colorization in SD, Full-HD, and 4K. Palette documents integrations with iPhone photos, Google Drive, Dropbox, and other photo apps, as well as a Windows desktop application from Covenant that uses its colorization engine. Its API platform has changed to RapidAPI. Uploaded files are processed securely and deleted shortly after results are provided. The terms say users retain ownership of images and videos they create and may use them commercially without restrictions. Palette has a free trial credit and plans costing $49 once or $72 per year.
