Getting Started
Install: pip install rembg. Single image: rembg i input.jpg output.png. Batch: rembg p input_folder output_folder. That is the whole learning curve for 80 percent of use.
The model behind it (U2-Net) is downloaded on first run; you can switch models including SAM-based ones for tricky edges like hair. For product photography, add onnxruntime GPU for 5-10x speedup. Integration: the Python API is two lines - from rembg import remove; output = remove(input_bytes) - so it slots into any automation pipeline.
