Most online background removers upload your photo to a cloud GPU. RatPDF's AI background remover is different: segmentation runs in your browser with ONNX Runtime Web — your image bytes never leave your device.

Why on-device matters

Privacy — headshots, ID scans, and unreleased product shots stay local
Resolution — output PNG matches original width and height
No queue — no server-side batch limits during peak hours

Trade-offs

First load downloads the model (~few MB). Processing speed depends on your CPU/GPU. Fine hair and glass edges remain challenging for any AI cutout.
