How to Use Signal Messenger’s Face Blurring Photo Feature

Encrypted messaging app Signal features a face-blurring feature that automatically locates and blurs faces in images shared over the chat platform.

It’s a neat tool to help protect the privacy of the people in the photos you share, and all processing involved in the blur feature happens locally on the device to maintain privacy.

Not only does it make it easy to give every face a hiding place, it can also be used to draw a fuzzy trace over something you want to erase. The following steps show you how to use it.

  • Bear in mind that the feature isn’t perfect, and won’t detect every face all of the time.


    To compensate for these flaws, Signal’s image editor also includes an option to manually obscure faces and other areas of a photo with a blur brush.
