## About

## What it does
Image Colorizer turns a grayscale or desaturated image into a colorized version. Send a binary image file up to 20 MB, choose a palette, and control how strongly the palette is applied.

The service accepts one required `file` in the request body. You can set `palette` to `natural`, `warm`, `cool`, or `sepia`, and tune `strength` from 0 to 1. The default palette is `natural`, and the default strength is `0.72`, which gives you a balanced result without overcooking the image.

Use Image Colorizer when you need to restore archived photos, produce stylized variants for editorial work, or create quick visual previews from black-and-white assets. It is useful anywhere you need a color output from a source image without building your own image-processing pipeline.

The response is a binary image, so you can store it, forward it, or pass it into the next step of your workflow.
