FAQ

Is my image uploaded?
No. Image decoding, model inference, alpha mask generation, and PNG export all happen locally in your browser.
Does it work for every image?
This version uses MODNet, so portraits are the most stable case. Products, animals, and complex objects may need a general segmentation model later.
What if WebNN is unavailable?
Auto mode tries WebNN NPU first, then WebNN GPU, then WASM. WASM is more compatible but slower.
