Kiwix is an offline reader for web content. It's software intended to make Wikipedia available without using the internet, but it is potentially suitable for all HTML content. Kiwix supports the ZIM format, a highly compressed open format with additional meta-data.

Kiwix is free software, which means you can freely copy, modify and distribute it.

Kiwix is mostly installed in schools, universities and libraries which can't afford a broadband Internet access. It is much faster than the Internet and also can be used by many institutions to save bandwidth and reader's time. But many people use Kiwix for their own personal purposes, for example, of people suffering from censorship or prisoners.

Kiwix is really easy to use. It provides a range of features which make usage comfortable:

Full text search engine

Bookmarks & Notes

HTTP server

PDF/HTML export

User interface in more than 100 languages

Tabs navigation

Integrated content manager and downloader

More features...

Kiwix is small and efficient software, usable on lower powered or old computers. It runs on a large range of operating systems, on Android and on the three main PC operating systems: Microsoft Windows, Apple Mac OS X and GNU/Linux distributions.
