The ZIM format was designed to deal efficiently with hugh amount of data, that means that you may deal with millions of pictures and text extremly quickly also on a small device like a smartphone.

The ZIM format was choosen by the top actors around Mediawiki to provide a offline usable versions of the content. 3.4 4 - Integrating Collection and DumpHTML extensions and new features.
