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 Zoom Web App

Due to support for ChromeOS apps are being phased out across all operating systems by November 5, 2022, Zoom has released the Zoom for Chrome Zoom Web App, which is intended to replace the ChromeOS Zoom app. We strongly recommend admins begin migrating users from the ChromeOS app to the new Zoom for Chrome Zoom Web App to ensure a smooth transition.
