What it supplies: Rembg is a tool to remove image backgrounds. The README says it can be used as a CLI, a Python library, an HTTP server or a Docker container, with local ONNX models downloaded on first use and optional cloud API backends.

Useful for: - Remove the background from a single image with rembg i, or batch a folder with rembg p, including a watch mode for new files.
- Return only the mask, apply alpha matting, or remove colour fringing from soft edges.
- Run an HTTP server with rembg s and call its remove endpoint with a URL or an uploaded file.
- Feed raw RGB24 frames from FFmpeg into rembg b to cut backgrounds from video frames.

First action: - Check Python is 3.11 or newer and below 3.14.
- Install one backend: pip install "rembg[cpu,cli]" (or gpu or rocm for NVIDIA or AMD).
- Run rembg i path/to/input.png path/to/output.png.
- Choose a model with -m, for example u2netp.

Prerequisites and limits: Python >=3.11 and <3.14. Choose one of the CPU, NVIDIA GPU or AMD ROCm backends; the README says NVIDIA GPUs may need onnxruntime-gpu, CUDA and cudnn-devel, and to fall back to the CPU backend if that does not work. Models download to ~/.rembg/models/ on first use.

- The withoutbg and Atlas Cloud backends are paid cloud APIs; the README says the Atlas job is asynchronous and can take over a minute per image.
- On the server, remote models are off by default because requests without their own key are billed to the key set in the server's environment.
- The README does not report quality or speed measurements for the models.
- The width and height given to rembg b must match FFmpeg's output dimensions.

The README states rembg is licensed under the MIT License, copyright Daniel Gatis. Each downloadable model has its own source and terms that the README links but this reference did not read, so check the model you use. Images you process carry their own rights.
