You cannot use Zoom on a laptop without downloading the application. Zoom is a software-based video conferencing platform, meaning it requires a dedicated program to function.
While you can join Zoom meetings directly from a web browser, this option is limited in functionality compared to the desktop app. You won't be able to access all features, such as screen sharing, recording, or breakout rooms.
Therefore, downloading the Zoom application is necessary to fully utilize its capabilities on your laptop.
