How does the face detection work?

The tool uses face-api.js, an AI-powered face detection library that runs entirely in your browser. It detects faces using a lightweight neural network model, then applies a blur or pixelation effect over each detected region.

What blur styles are available?

Three styles are available: Gaussian Blur (smooth blur), Pixelate (mosaic-style blocks), and Solid Fill (covers the area with a customizable solid color — black, white, or any color you choose).
