The Recraft Remove Background node uses Recraft's API to intelligently detect and remove image backgrounds, creating images with transparent backgrounds and corresponding alpha masks.

## Parameters

### Basic Parameters

| Parameter | Type  | Default | Description                           |
| --------- | ----- | ------- | ------------------------------------- |
| image     | image | -       | Input image to remove background from |

### Output

| Output | Type  | Description                                          |
| ------ | ----- | ---------------------------------------------------- |
| IMAGE  | image | Image with background removed (with alpha channel)   |
| MASK   | mask  | Mask of the main subject (white areas are preserved) |
