Face Detection and Privacy: Blurring Faces in Photos

Face blurring is essential for privacy compliance when sharing photos that include bystanders or minors.

Why Blur Faces?

How Face Detection Works

Modern face detection uses convolutional neural networks (CNNs):

1. The image is scanned at multiple scales

2. A sliding window evaluates each region

3. The CNN classifies whether each region contains a face

4. Non-maximum suppression removes duplicate detections

Blur Techniques

Our Face Blur tool offers both Gaussian and pixelation styles with adjustable intensity.

For a complete privacy workflow, run your photos through the EXIF Remover after blurring faces to also strip GPS coordinates and device identifiers.
