bgbgone

bgbgone is a background remover for macOS. It takes an image in and returns an image out, using Apple Vision masks and Core Image on-device, with no cloud, no account, and no telemetry. The site describes it as a UNIX-style tool that is 100% on-device and 100% scriptable.

Its command-line interface supports direct file input, piping through standard input, and batch processing folders. Output can be written as a transparent PNG by default, sent to standard output, or placed in a chosen directory. The available flags include background replacement with a solid colour or an image, edge feathering, mask-only output, crop and padding controls, subject type hints such as person, product, car, animal, graphic, and transportation, multi-instance cutouts, several output formats, and a local HTTP API server. The example and flag listings also mention filters and effects such as grayscale, blur, zoom blur, outline, and drop shadow.

bgbgone is delivered as a 3 MB binary for macOS 26+ and Apple silicon. It can be installed with Homebrew, and the page also offers a native macOS app for users who prefer a window instead of flags. The app is described as signed and notarized, free, open source, and able to process a dropped folder into a folder of clean cutouts. The project is released under the MIT license.
