How Face Detector works

Uses TensorFlow.js with the BlazeFace model for ultra-fast face detection. Detects faces with bounding boxes and 6 key landmarks (eyes, ears, nose, mouth). Processing runs in your browser via WebGL — images never leave your device.

Frequently asked questions

Is this face detector free?

Yes. 100% free with no signup or limits.

Are my photos uploaded to a server?

No. Detection runs in your browser and images stay on your device.

Can it detect multiple faces?

Yes. It detects and labels each face with a confidence score.

How accurate is it?

It works best on clear, front-facing faces. Small, blurry, or occluded faces may be missed.

Does it work on side profiles or group photos?

It performs best on well-lit faces. Extreme angles or crowded photos can reduce accuracy.

Do I need internet?

The model loads in your browser on first use, so internet is required once. After that it may be cached.
