Illustrative view
Edge-connected background colors become transparent without uploading the image.
The background remover runs a quantized MODNet portrait-matting model through ONNX Runtime Web. The model creates a soft transparency mask that separates a foreground subject from its surroundings without sending the image to a server.
The subject threshold controls how confidently a pixel must belong to the foreground. Edge softness preserves partial transparency around hair and fine details. The full-resolution source is combined with the AI mask and exported as a transparent PNG.

Reusable transparent product image
MODNet is optimized for people and portrait-style foregrounds. Clear single products may also work, while crowded scenes, transparent objects, and very fine structures can need additional editing.
No. The ONNX model and WebAssembly runtime execute in your browser. Only the reusable model files are downloaded; the selected image stays on your device.
No. This tool runs locally in your browser, so the values or files you provide are not sent to a ToolStack server.
