Now you can make calls directly from your browser

What is it

This is a new feature in the web client that allows you to initiate and receive voice and video calls directly in your browser, without having to download and install a separate desktop app. Initially, this feature is available for individual chats, but full support for group calls is planned.

Key features of future group calls:

• Up to 32 participants in a single group video conference
• Support for call invitation links
• Call scheduling
• Full integration with the existing chat interface

Why is it needed

Initiating calls in WhatsApp Web isn’t just adding a button; it fundamentally expands the messenger’s use cases.

1. Freeing Linux users from their phones. Millions of Linux users have been limited to the text-based interface of WhatsApp Web. Now they can fully participate in video calls, hold meetings, and chat with colleagues directly from their browser, without switching to their mobile device. This is a huge step for enterprise users and open source enthusiasts.
2. Unified workspace. Windows and macOS users who prefer to work in a browser rather than a desktop app finally have a single entry point for all communications—messages and calls. No more holding your phone nearby or switching between different apps.
3. Screen sharing for presentations and support. The built-in screen sharing feature works right in the browser. It’s the perfect tool for quick presentations, document discussions, remote technical support, or co-browsing content. All you need is an active video call and trust in the other person.
4. Unified security standard. All calls made through the web client are protected by end-to-end encryption using the Signal protocol. No additional configuration is required—security is enabled by default, just like on mobile platforms.

How it works

The calling interface is integrated into the familiar WhatsApp Web design and requires no training.

• You can start a call directly from a private chat by tapping the phone icon (voice call) or camera icon (video call).
• During a video call, a screen sharing button is available. By tapping it, you can show your interlocutor any content—from a presentation to a browser tab.
• End-to-end encryption is automatic, ensuring that no one, including WhatsApp and Meta, has access to the conversation content.
• No additional plugins or apps are required to get started—all you need is a modern browser.

Availability and Development Plans

The WhatsApp Web calling feature is undergoing final testing and is already available to some users participating in the beta testing program.

In the coming weeks, WhatsApp plans to:

• Expand to more users within the beta program
• Begin a gradual rollout to users outside the beta program
• Once individual calls have stabilized, launch support for group calls with expanded capabilities

Full support for group calls, invitation links, and scheduling is expected after completing basic functionality testing.

Conclusion

The launch of WhatsApp Web calls marks an important step in the platform’s evolution. The web client is no longer a stripped-down version for text messaging and is becoming a full-fledged communication hub, equal in capabilities to the mobile and desktop apps.

This update is especially valuable for Linux users, who finally have equal access to all the messenger’s features. For everyone else, it’s a step toward further unification of the workspace, where phones, tablets, and computers work together as a single ecosystem.
