How does the background remover work?

It uses a neural network (U2Net) running directly in your browser via WebAssembly. The AI model detects the foreground subject and creates a precise mask to separate it from the background. No data is sent to any server.

Why does the first use take longer?

On first use, the AI model (~44MB) is downloaded and cached in your browser. Subsequent uses load the cached model instantly.

Are my images uploaded to a server?

No. All processing happens 100% in your browser using WebAssembly and ONNX Runtime. Your images never leave your device.
