Zoom system requirements: PWA and web client

Last Updated:

This article lists the requirements for using the Zoom Progressive Web App (PWA) and browser-based web client on Windows, macOS, Linux, Android, and iOS. This allows you to join and participate in meetings and webinars without needing to install the full Zoom app, instead connected through your web browser.

This article covers:

Supported operating systems

  • Desktop operating systems
    • macOS X with macOS X (10.10) or later
    • Windows 11
    • Windows 10
    • Windows 8 or 8.1
    • Windows 7
    • ChromeOS
    • Ubuntu 12.04 or higher
    • Mint 17.1 or higher
    • Red Hat Enterprise Linux 6.4 or higher
    • Oracle Linux 6.4 or higher
    • CentOS 6.4 or higher
    • Fedora 21 or higher
    • OpenSUSE 13.2 or higher

Processor requirements

    • (Recommended) Dual-core 2Ghz or higher (Intel i3/i5/i7 or AMD equivalent)
  • Mobile devices
    • Any 1 Ghz single core processor or better (non-Intel)

Supported web browsers

  • Desktop
    • Chrome: Within 2 versions of current version

    • Edge: Within 2 versions of current version
    • Safari: Within 2 versions of current version
  • Mobile
    • Safari: Within 2 versions of current version
    • Chrome: Within 2 versions of current version
    • Firefox: Within 2 versions of current version

As an example, if the current version of Chrome on mobile is 111, then the PWA is supported on versions 109, 110, and 111. As new versions are released, the minimum version will also follow behind by 2 versions.

Notes:

  • These are the officially supported web browsers. The PWA and web client may work in other browsers, but those browsers are not officially supported and may vary in terms of compatibility and functionality.
  • For web browsers, older versions may also still work, but for best results, we recommend keeping within 2 versions of the current version.
