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.
