Signal Desktop Overview

Signal Desktop is the free desktop companion for Signal, a privacy-focused messaging app, available for Windows, macOS, and Linux. Signal is widely regarded for strong privacy: all messages, voice calls, and video calls are end-to-end encrypted by default using the open-source Signal Protocol, and the app collects minimal metadata. It supports one-on-one and group chats, disappearing messages, voice and video calls, and file sharing. Signal is developed by the non-profit Signal Foundation and funded by donations rather than advertising. The desktop app links to your phone number account and installs without an internet connection during setup, though messaging requires connectivity. It also supports stickers, reactions, and link previews while keeping its privacy-first defaults intact. You can reach the official Signal Desktop download from Signal via the link on this page.
