In Opera Mini, there are two modes of data compression





Opera Mini mobile browser now offers the user two different data compression modes: Extreme Mode and High mode . Both are ultimately aimed at reducing the size of the data of the requested web pages, which may be required with limited and expensive volumes of mobile traffic. The difference between the modes is how much each of them compresses the data and thus how much a particular web page loses from its original appearance due to the removal of “noncritical” fragments from the markup.



When you turn on Extreme Mode, the data, including images, will be subjected to maximum compression: the economy of traffic here can be up to 90%. At the same time, however, the appearance of the web page may change significantly. High mode is more sensitive to HTML content - the level of image compression is reduced and video players are skipped, but the level of data compression is on average 30-40%. The user can choose between both modes, guided by what network he is in.
