rembg

rembg is an open source tool that removes the background from images. It can be used from the command line, as a Python library, as a local HTTP server, or inside a Docker container.

rembg separates the subject of an image from its background and returns the subject with a transparent background. Because it runs on your own machine or server, images do not need to be sent to a third-party service. The project includes a sponsor-backed background remover API for those who prefer a hosted option.

• Remove backgrounds on your own machine
• Use it as a command line tool
• Import it as a Python library
• Run a local HTTP server
• Run it in a Docker container

Developers, data teams and hobbyists who want to automate background removal in their own pipeline. It is a good fit when you want control over where images are processed.

The project is open source under the MIT licence. You provide the computing resources, so speed depends on your hardware. Setup involves Python packages and model downloads, which suits people comfortable with the command line.
