# Background removal

Remove the surrounding background while keeping the source subject. This fits catalog images, presentation assets and profile cutouts where you already have the right photograph. It does not invent a new setting or replace objects; those jobs require image editing or generation.

## Inputs & outputs

### Background removal

- ### Required input

An image file. The CLI can convert a local file into a base64 data URL for the request.

- ### Result

An image artifact intended to preserve a transparent background, plus its MIME type and provider.

- ### Configured bounds

The capability catalog specifies a 60-second timeout and a 20,000,000-byte limit. Inspect fine edges on both light and dark backgrounds.

## Tool usage

Tool charges use the same configured cost basis and 2× multiplier as billing. Model and runtime charges are separate.

Background removal uses a provisional flat cost.

- ### rembg.remove-background

$0.01 per asset.
