Palette vs PixGrid Colorize Photo

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.

PixGrid Colorize Photo is a browser tool for restoring color to black-and-white or badly faded photographs, including skin, hair, and clothing. Restore Color applies color in one step without extra sliders. PixGrid recommends repairing scratched or dusty prints with Fix Old Photo before colorizing. It says sharp scans work better than dim or crooked phone photos and advises checking faces before printing. Each black-and-white colorization uses 2 AI credits. The browser colorizer is free to open, while restore actions consume credits through one-time passes. The Free plan costs nothing and exports watermarked files. Day Pass costs $2.99, paid once for 15 credits and unwatermarked exports for 24 hours. Pro Month costs $9.99, paid once for 120 credits and unwatermarked exports for 30 days. Ultra Pass costs $29.99, paid once for 500 credits and unwatermarked exports for 30 days. Paid passes do not auto-renew. Chrome, Safari, Firefox, and Edge are supported.
