Google Meet, Google’s video conferencing and online meeting platform, allows users to host and join virtual meetings, collaborate with colleagues or friends, and communicate via audio and video calls. In addition, Google Meet offers a number of features that facilitate online communication, one of which is the “picture-in-picture” function.
You can use Google Meet’s “ picture-in-picture ” feature to have a compact, mobile version of the user interface that remains visible on top of any content you’re navigating to. Using picture-in-picture, you can easily continue to actively participate in a meeting while switching to a different tab or window.
