What it is
Palette is a photo colorization service that adds realistic colors to uploaded images. In its web app, users choose from more than 21 filters and can refine colors with descriptions and keywords. Palette also supports batch processing, and says a simple script can colorize over 1 million images per day. Its API offers automated or custom prompts, reference images, and up to 120 prompts for one image. Each image is limited to 4K resolution and 10 MB. A beta Video API supports colorizing video frames in SD, Full-HD, and 4K. Palette documents integrations with iPhone photos, Google Drive, Dropbox, and other photo apps, alongside a Windows desktop application from Covenant that uses its colorization engine. Its API platform has changed to RapidAPI. Uploaded files are securely processed and deleted shortly after results are provided. Users retain ownership of created images and videos and may use them commercially without restrictions. The free plan includes one trial credit, unlimited watermarked previews resized to 500x500px. Paid plans include a $49 one-time option and a $72 per year subscription.
