BiRefNet — complete background removal on Replicate

The full BiRefNet model zoo behind one endpoint: all 10 official variants plus ToonOut for anime/stylized art. Returns a transparent cutout or a raw matte. MIT-licensed — free for commercial use.

Highlights

  • 11 models, one input — switch with variant; one warm container serves them all.
  • Anime / illustration — variant=toonout handles hair wisps, line art, and translucency that general removers smear.
  • Animated GIF & WebP — multi-frame inputs are matted frame-by-frame and returned as an animated WebP with full transparency (frame timing + loop preserved).
  • Real controls — cutout (RGBA) or raw mask; grow / shrink / blur the matte; refine foreground colours; pick inference resolution.
  • MIT / commercial-OK — unlike BRIA-based removers, the output is free to use commercially.

Inputs

  • image — any image; animated GIF/WebP supported (→ animated WebP output).
  • variant — which model (table above). Default general.
  • resolution — square inference size; 0 = the variant’s native resolution.
  • output_format — cutout (RGBA) or mask (raw alpha matte).
  • mask_blur / mask_offset — soften / grow / shrink the matte.
  • refine_fg — FB blur-fusion to strip background bleed on soft edges.
