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.

Can I manually select areas to blur?

Yes. In addition to automatic face detection, you can click and drag on the image to manually draw blur regions. This is useful for blurring license plates, name tags, or other sensitive information.

What blur styles are available?

Three styles are available: Gaussian Blur (smooth blur), Pixelate (mosaic-style blocks), and Solid Fill (completely covers the area with a solid color).
