Signal for PC is an instant messaging app that allows you to send messages, photos, videos, files, make audio and video calls directly from your computer. Because it uses state-of-the-art end-to-end encryption technology and is open-source, Signal is considered one of the most secure instant messaging desktop applications worldwide. Powered by innovative technology and a very user-friendly user interface, you will love how private will become your conversations.

Key features

  • State-of-the-art privacy: Everything in Signal, including messages, voice memos, shared files, images, videos, and calls, is end-to-end encrypted using state-of-the-art technology. Absolutely no third parties or Signal have access to these types of information.

  • Group chats: Using Signal, you can easily create group chats of up to 1000 people. Each new participant must accept the invitation to be part of the group.
  • Handy private notes: You can also use end-to-end encryption to send private notes to yourself so that they remain confidential. Like a regular chat with yourself, you can send text, photos, messages, files, etc. Only you will be able to consult them on your PC and linked devices.
  • Dark mode: A nice-looking but straightforward user interface is used. It also features a dark mode to enjoy the app without feeling eyestrain.
  • Excellent audio quality: You can make audio and video calls worldwide directly from the desktop application with stable and high audio and video quality.

How does Signal for PC work?

How secure is the Signal application?

It means that the application's source code is available for everyone so that any security breach can be reported and fixed.
