RMBG

What RMBG is
RMBG is an image background removal application available on the web and for Windows, Linux, and macOS, with API access also listed. It uses open-source AI models to separate subjects from backgrounds, and users can choose among supported matting models to suit different images. Documented options include U2-Net, U2-Netp, U2-Net Human Segmentation, U2-Net Cloth Segmentation, Silueta, Isnet General Use, and BRIAAI RMBG. The app also supports batch processing and replacement backgrounds.
RMBG says image processing happens locally rather than uploading images to servers, which its maker says helps keep them private from potential leaks. The project describes the application as open source and free; its GitHub page identifies the license as MIT. The web tool accepts up to 20 images at a time, each no larger than 5 MB. The download section links to web and desktop versions, while Stack Overflow and GitHub Discussions are available for community support. The Free plan is listed at 0.00 USD.
