BG0
BG0 removes photo backgrounds in a browser and downloads the result as a transparent PNG.
What BG0 is
BG0 removes photo backgrounds in a browser and downloads the result as a transparent PNG. It supports PNG, JPG, WebP, HEIC, and HEIF images up to 40 MB, and image bytes remain in the browser rather than being uploaded for processing. The remover runs BiRefNet and can switch to BiRefNet-lite if the selected model cannot run. First use requires an internet connection to download and prepare the model; the browser can cache it for later visits. BG0 is free, with no account, credits, subscription, or stated usage limit. Developers can use the @bg0/browser library to add on-device removal to a web app without a server or API key, using WebGPU or WebAssembly. Its documented iOS path uses a single-threaded WebAssembly worker and BiRefNet-lite, with output capped at 1280 pixels on the longest edge. The remover has no manual touch-up editor. BG0 uses PostHog for anonymous analytics and says session recording, advertising, fingerprinting, and automatic click capture are disabled.
