RMBG

RMBG is an open-source browser-based background removal tool that processes photos locally on-device.

RMBG is a free, open-source background removal tool that runs directly in the user's web browser. It uses the BiRefNet-lite model to process images entirely on-device, ensuring that image bytes are never uploaded to a server. The application supports input formats including PNG, JPG, WebP, AVIF, BMP, and GIF, and exports to formats such as PNG, WebP, JPEG, and AVIF. Users can refine cutouts using brushes, guided clicks, and region recomputation, as well as handle batch processing for up to 24 images. The tool is designed for anyone needing privacy-focused image editing with fine control over transparency and masks.
