We’ve mentioned Signal Messenger before in quite a few guides. Signal is a free and open source, cross-platform encrypted messaging service developed by the Signal Foundation and Signal Messenger LLC.
It uses the Internet to send one-to-one and group messages, which can include files, voice notes, images and videos. Its mobile apps can also make one-to-one voice and video calls, and the Android version can optionally function as an SMS app.
With the new update, Signal has introduced a new blur feature in the image editor that can help protect the privacy of the people in the photos you share. It’s now easier than ever to give every face a hiding place, or draw a fuzzy trace over something you want to erase. To use it, all you need to do is to simply tap on the new blur tool icon to get started.
