Frequently Asked Questions
How are faces detected?
We use MediaPipe's BlazeFace model, running locally in your browser via WebAssembly. No image is sent to any server.
Does it detect multiple faces at once?
Yes — every detected face in the photo is anonymized in the same pass.
What if a face isn't detected?
Very small, side-profile or shadowed faces may be missed. Try a sharper, front-facing photo.
