Opera Max is a data-management and data-savings app that shrinks videos and photos on almost any app on mobile data connections and Wi-Fi to help you extend your data plan by up to 50% for free.

The App's unique technology saves data on videos without any significant loss in quality and even reduces buffering. You can also choose to block apps from using background or foreground data when the app is not in use or when you are roaming and want to spend data only on a few, choice apps.
