How to change your Zoom background on the desktop app

Download the Zoom app for Mac or Windows
Open the app and sign in.
Click your profile picture, then click on Settings.
In the left menu bar, click on the Virtual Background tab (if you don't see this tab, log in to the Zoom website, go to Settings and toggle on Virtual Background).
In the Virtual Background tab, select one of Zoom's defaults or upload your own image.
If you have a green screen set-up, you can select that option.
To add your own image or video, click the + icon to upload from your computer.
