Webinars are built for presenting polished content to a large audience, whereas meetings are built for small to large team discussion and collaboration.
Large Meetings is an optional add-on for Zoom’s meeting plans to scale up to 1,000 live interactive participants. In large meetings, all participants can share their audio, video, and screen.
Webinars are used to host virtual presentations and broadcast them to a view- and listen-only audience. This reduces the risk of disruptions and is a safer choice for large audiences who join mostly to listen and learn.
