How does the background remover work?

We use AI models that run entirely in your browser via WebAssembly. You can pick an engine tuned for general photos, portraits, anime art, or fast previews. No image is ever sent to a server.

Which AI engine should I use?

General (recommended) works for most images. Choose Portrait for people and passport photos, Anime & Art for illustrations, or Fast Preview for a quick draft. All engines are free and run locally.

What image formats are supported?

JPG, PNG, and WebP images are supported. Output can be WebP (recommended, ~70% smaller) or PNG (lossless, max compatibility).

Why does it take a while the first time?

The first time you use an engine, its AI model (5—176 MB depending on choice) is downloaded and cached in your browser. Subsequent uses are much faster.

Is my image uploaded to any server?

No. All processing runs locally in your browser. Only the AI model weights are downloaded once per engine — your photos never leave your device.

How does the background removal work?

The tool uses the ISNet deep learning model running locally in your browser via ONNX Runtime Web and WebAssembly. It analyzes the image and creates a mask separating the foreground from the background.

Why does it take time on first use?

The AI model needs to be downloaded once (approximately 40 MB). After the first use, it is cached in your browser and subsequent removals are much faster.

Is my photo uploaded to a server?

No. The entire AI model runs in your browser. Your photos never leave your device.

Can I use the result commercially?

Yes. The tool is free to use and the output images are yours to use for any purpose.
