Zoom (stylized as zoom) is a videotelephony proprietary software program developed by Zoom Video Communications. The free plan provides a video chatting service that allows up to 100 concurrent participants, with a 40-minute time restriction. Users have the option to upgrade by subscribing to a paid plan. The highest plan supports up to 1,000 concurrent participants for meetings lasting up to 30 hours.

During the COVID-19 pandemic, there was a major increase in the use of Zoom for remote work, distance education, and online social relations. The increase led to Zoom being the 5th most downloaded mobile app worldwide in 2020 at 477 million downloads.

Zoom is compatible with Windows, macOS, iOS, Android, Chrome OS, and Linux. It is noted for its simple interface and usability, regardless of technological expertise. Features include one-on-one meetings, group video conferences, screen sharing, plugins, browser extensions, and the ability to record meetings and have them automatically transcribed. On some computers and operating systems, users are able to select a virtual background, which can be downloaded from different sites, to use as a backdrop behind themselves.

Use of the platform is free for video conferences of up to 100 participants at once, with a 40-minute time limit if there are more than two participants. For longer or larger conferences with more features, paid subscriptions are available,
