Messages, files, pictures, videos, stickers…everything is encrypted. Everything that goes through the Signal desktop app gets encrypted. Linux: Follow the instructions to configure the Signal repository and install the Signal package. Non-admin users should search for /Applications using Spotlight and move Signal's install file into that directory.

macOS: Move Signal to the Applications folder. It can only be turned back into a readable message when it hits the intended recipient’s Signal app. Windows: Follow prompts from the install link. What you see as your message gets turned into something indecipherable when it leaves your phone. The cornerstone of Signal’s security is the end-to-end encryption.
