How do I blur faces in a photo?

Upload your photo and click "Detect & Blur Faces". The AI automatically finds all faces and applies a pixelation blur to anonymise them. All processing happens in your browser.

Is the face blurring tool free?

Yes, completely free with no account required and no watermarks.

Are my photos private?

Yes. Face detection runs 100% in your browser using TensorFlow.js. Your photos never leave your device.

Can it detect multiple faces?

Yes, the AI can detect and blur up to 20 faces in a single image simultaneously.

Why pixelation instead of Gaussian blur?

Pixelation (mosaic effect) is a stronger form of anonymisation than blur. It cannot be reversed to recover facial features, making it the preferred choice for privacy protection.
