What RMBG is

RMBG is a free, open-source image background removal application for web, Windows, Linux, and macOS, with API access. It uses open-source AI models for image matting and lets users switch among supported options, including U2-Net, U2-Netp, U2-Net Human Segmentation, U2-Net Cloth Segmentation, Silueta, Isnet General Use, and BRIAAI RMBG. RMBG says processing happens locally and images are not uploaded to servers; its maker says this keeps images private from potential leaks. Listed capabilities include batch processing, replacement backgrounds, and API access. The web tool accepts up to 20 images, each up to 5 MB. Desktop downloads are available for Windows, Linux, and macOS, alongside a web version. The project’s GitHub page identifies an MIT license. Community support links point to Stack Overflow and GitHub Discussions. The Free plan is listed as free, with the web tool’s 20-image and 5 MB limits. Platforms listed are API, Linux, macOS, web, and Windows.
