"Zoom" in a Chrome extension search can mean the video meeting platform, the separate ZoomInfo contact database, or Chrome's own page zoom feature. These are unrelated tools, so the right extension depends entirely on which one you are looking for.
Scheduling and joining Zoom meetings
Zoom's own Chrome extension, published by Zoom itself, lets you schedule and start meetings from your browser toolbar and shows your upcoming meetings without opening the desktop app. Install it directly from the Chrome Web Store listing published by Zoom, and avoid unofficial extensions claiming similar features.
Finding contacts with ZoomInfo
ZoomInfo is a separate business contact and company database, unrelated to Zoom's video platform, with its own Chrome extension for looking up company and contact details while browsing LinkedIn or company websites. It is a paid B2B sales tool, not a free consumer extension.
Zooming in on a web page
Chrome already includes page zoom controls in its main menu and with the Ctrl and plus or minus keyboard shortcut, which covers most needs to make text and images larger without installing anything. A dedicated zoom extension only adds value if you want a persistent on-page magnifying tool for images.
