Send messages, make voice and video calls, create group conversations, and share files with end-to-end encryption built into the way Signal communicates.
Signal combines everyday messaging features with privacy protections that apply automatically, so personal conversations, calls, groups, and shared media stay in one focused communication app.
Signal uses end-to-end encryption powered by the open-source Signal Protocol. Messages and calls are protected automatically, which means Signal cannot read your message content or listen to your calls. Privacy is part of the communication system itself rather than an optional setting you need to turn on for each conversation.
Send text, voice messages, photos, videos, GIFs, and files from the same conversation. Signal uses an internet connection for communication, making it practical for personal chats and regular contact across different locations.
Start one-to-one voice or video calls without moving to a separate calling service. Calls use the same privacy-first communication model, so messaging and calling remain part of one consistent experience.
Use media, files, voice messages, GIFs, and encrypted stickers to add context and expression to a conversation. Signal keeps these sharing tools close to the message thread instead of turning communication into a collection of separate services.
Create group chats for family, friends, communities, or coworkers. Participants can keep an ongoing conversation together while using the same messaging and privacy model available in individual chats.
Signal does not depend on advertising inside the app. There are no ads or affiliate marketing, and conversations are not turned into advertising profiles. The result is a communication experience that stays focused on the people and messages in front of you.
Signal is developed by an independent nonprofit organization and supported by grants and donations. Its funding model is separate from advertising, which allows the product to keep privacy and communication at the center of its development.
Signal is designed for conversations that may look different from one person to the next, while keeping the same private messaging foundation across direct chats, calls, groups, and shared content.
Private conversations
One-to-one messaging
Keep everyday conversations in a private messenger where text, voice messages, photos, videos, and files can stay together in a single thread.
Group coordination
Friends, family, and teams
Use group chats when several people need the same conversation, whether the goal is planning, staying in touch, or keeping shared information easy to follow.
Private calling
Voice and video
Move from messages to voice or video calls without changing communication tools, while keeping calls protected by end-to-end encryption.
File and media sharing
Photos, videos, and documents
Share media and files directly inside a conversation so the material you are discussing remains connected to the people and messages it belongs with.
Focused communication
Without advertising noise
Use a messenger without in-app advertising competing for attention, making it easier to stay focused on conversations instead of promotional content.
Privacy by default
Built into communication
Messages and calls use end-to-end encryption automatically, so private communication does not depend on remembering to enable a separate protected mode.
Choose Signal when you want messages, calls, groups, and shared media in one privacy-focused messenger.
