What is rembg-webgpu exactly?

It's a WebGPU-accelerated port of the rembg deep learning model for browser-based background removal, handling inference on-device with ONNX Runtime.

Can this background remover work offline?

Yes, after the initial model download and caching via Service Worker, all processing happens locally without internet.

Often — no network latency means instant results on capable hardware, though first load takes time.

Best on Chrome with WebGPU enabled; partial in Firefox, experimental elsewhere.
