## What it is
A Python SDK (pip install withoutbg) for removing image backgrounds, offering a free local open-weights ONNX model and an optional paid cloud API behind the same interface. It returns PIL RGBA images, supports batch processing, and includes a CLI for one-off removals.

## Use cases
- remove background from a photo in python
- make image background transparent locally without uploading
- batch remove backgrounds from a folder of images
- extract alpha matte for compositing
- cut out product photos for e-commerce listings
- remove background from car photos with shadows
- offline background removal with no api key

## When to choose
- you want free, private, offline background removal in Python with a simple API
- you need batch processing in scripts, notebooks, or backends
- you want to start locally and switch to a higher-quality cloud API with one line

## When to avoid
- you need a GUI editor for manual cutout refinement
- you need non-Python languages or non-image matting tasks
- you cannot download ~455 MB of model weights locally and don't want a paid API
