Blur Face allows you to quickly and easily anonymize faces in your images.
It detects faces in the selected image and offers to anonymize them with one of three censoring options: blur, pixelate (a.k.a. mosaic), or a plain black square.
Do you want to blur something else in the image? No worries.
You can manually set new blur zones to censor whatever you wish.
Common application scenarios
• Personal: You want to share one of your images (friends, family, etc.), but want to conceal some people's faces to protect their privacy.
• Artist/photographer: You wish to protect the anonymity and privacy of people in your photographs by blurring their faces or other portions of the image.
• Teachers: You want to share images from your most recent field trip, but you need to hide the faces of your students/pupils to safeguard their privacy.
Using this simple yet powerful photo editor, you can simply pixelate or blur a person's face in a photograph.
