Remove Background
100% Private AI

Frequently Asked Questions

• How does the AI background remover work?

  It uses a neural network model in ONNX format, processed locally via ONNX Runtime Web and WebAssembly. The AI identifies the subject and separates it from the background — all inside your browser.

• Does it upload my images to a cloud service?

  No. The model runs entirely on your device. Your images are never sent to any server. This is what makes it 100% private.

• Why does it need to download a file the first time?

  The AI model (~40 MB) needs to be downloaded once to your browser cache. After that, it works fully offline for all future uses without re-downloading.

• What types of images work best?

  The tool works best on images with a clear foreground subject — such as people, pets, products, and animals — against a relatively distinct background.

• What output format is used?

  The result is always exported as PNG to preserve the transparent background layer, even if the original was a JPG.

• Is the background remover free?

  Yes, completely free. No subscription, no account, and no usage limits other than your device's processing capacity.
