System Requirements

You can start and join Zoom meetings through the Zoom web client (a browser) without downloading plugins or software. However, Zoom runs optimally when the Zoom desktop client (app) has been downloaded. Regardless of how you connect to Zoom, it is important to review system requirements for your device to ensure that you will be able to use Zoom.

Zoom Web Client

The web client can help users who are limited in what they can install or download, allowing them to use their web browser and join Zoom meetings without downloading the application. By default, participants joining a meeting through the web client do not need to be signed-in to a Zoom account.

Chrome PWA

The Zoom for Chrome PWA (Progressive Web App) allows some of the same features available on the desktop client or mobile app within the Chrome web browser.

Note: The Zoom for Chrome PWA is separate from the ChromeOS app and is intended to replace it, as support for ChromeOS apps was phased out across all operating systems as of November 5, 2022.
