Auto HD|LQ for YouTube is an add-on for the YouTube application, which can automatically switch between High Definition (HD) and Low Quality (LQ) video modes. This is very useful if your Internet connection is slow. It is also great if you just want to see what the video is without wasting your bandwidth.

This is a simple and easy-to-use tool. You can install it on your desktop’s Chrome browser. If you want to automatically play Youtube videos in the selected quality, you can easily do so using the extension’s auto mode.
