WhatsApp just closed one of the last major gaps between its web client and its mobile app. Starting today, users can make and receive voice and video calls directly through WhatsApp Web, including group calls, without installing any desktop software, a feature that’s been in testing for months before finally rolling out broadly.
The addition matters most for anyone stuck on a locked-down machine. Work laptops that block app installs, shared library computers, or just people who’d rather stay in a browser tab can now join calls the same way they would on mobile, complete with the same end-to-end encryption WhatsApp uses everywhere else. Group calls carry over the existing 32-participant cap from the mobile app, so nothing’s been scaled back to accommodate the browser.
A handful of features go beyond a basic port, too. Call Transfer lets you move a live call from phone to browser or back without hanging up and rejoining, which is a meaningfully different experience from just ending one call and starting another. There’s also a new Waiting Room option for group calls made via link, letting hosts require approval before someone joins, plus QuickHD video that aims to deliver full HD quality within the first few seconds instead of ramping up gradually, and a toggleable noise suppression option for calls made from noisy environments.
The rollout is gradual rather than instant, so not everyone will see the call buttons on WhatsApp Web immediately. Given WhatsApp’s user base sits above 3 billion people globally, roughly a third of the world’s population, staged rollouts like this are standard practice to avoid overloading calling infrastructure all at once.
The bigger context here is competitive. Zoom, Google Meet, and Microsoft Teams have offered full browser-based calling for years, so WhatsApp closing this gap isn’t groundbreaking so much as overdue the company confirming it’s still treating Web as a primary client rather than an afterthought. If you’ve been keeping the desktop app installed purely for calls, this is the update that finally makes that unnecessary.
