How It Works

BiRefNet produces a high-resolution alpha matte with genuine hair-level edge detail — automatic roto without a green screen. The after side shows the subject composited onto a checker so you can see the cut edge. Use it for clean plates, compositing, or to isolate a subject before relighting or background replacement.
