Video quality

YouTube adjusts the quality of video stream based on the speed of your Internet connection (bandwidth). This is why you may notice that the quality of video changes as you watch videos.

To view the video in the best possible quality, change the video quality by going to Settings in the corner of the video player, and selecting the highest possible resolution.

Some browsers may only have one or two video formats to choose from.

Below are some browser and operating system combinations that support YouTube's high-quality video formats:

• Google Chrome (all operating systems)
• Internet Explorer or Edge on Windows 8.1 or newer
• Safari on Mac OS X 10.10 or newer
• Firefox on Windows 7 or newer and on Mac OS X 10.10 or newer
