Knowledge, Offline.

Kiwix has made a great selection of resources available to you Offline, for free!

Kiwix compresses the site’s content into ZIM files, which can be downloaded and used on any device thanks to the Kiwix app. The options are endless and our joint effort reflects all our organisations’ commitment to open, free, and unrestricted learning for all!

Wikipedia

Wikipedia is the world’s largest free online encyclopaedia, with millions of articles in hundreds of languages. Since its founding in 2001, it has become an essential resource for knowledge seekers worldwide.

Kiwix and Wikipedia share a strong partnership, formalised with the Wikimedia Foundation to expand offline access globally. This collaboration enhances Kiwix’s usability, integrates technical operations, and supports long-term reuse of its free access platform.

freeCodeCamp

Kiwix and freeCodeCamp have been working together to make coding education accessible anywhere, even without internet access. Through this collaboration, Kiwix now offers FreeCodeCamp’s JavaScript curriculum as an offline package, allowing anyone to learn programming skills from thousands of tutorials without needing to be online. This initiative is especially valuable for learners in remote areas, those with unreliable connectivity, or anyone who wants to study on the go.

The partnership aims to expand this offering to include the full range of FreeCodeCamp courses in multiple languages, further broadening offline access to high-quality coding education.

Kiwix Catalog FAQ

What do mini, nopic and maxi mean in the Wikipedia ZIM files?2026-03-03T13:41:51+00:00

File size is always an issue when downloading such big content, so we always produce each Wikipedia file in three flavours:

mini: only the introduction of each article, plus the infobox. Saves about 95% of space vs. the full version.

nopic: full articles, but no images. About 75% smaller than the full version.

maxi: the default full version.

Where can I find ZIM files?2026-03-03T13:50:31+00:00

ZIM files are available through the Kiwix app’s (Kiwix reader) built-in catalog or can be downloaded from the official Kiwix library. One can also generate custom ZIM files with tools like Zimit.

Can I update ZIM files incrementally?2025-06-18T09:48:48+00:00

No. Incremental updates for ZIM files (such as Wikipedia) are not currently available, but this feature is being explored for the future.

Does Kiwix make or sell content?2025-06-18T12:01:56+00:00

Kiwix developed a way to highly compress content and package it for easy online access, the ZIM format. We don’t sell content but make it freely available to download from library.kiwix.org. We offer apps to read the data (Kiwix Reader) and pre-selected apps for direct access to the type of information you may require (the Branded apps available from your apps stores), or turn your own Raspberry Pi into an offline network (Kiwix Server).

What we do sell is the online service of building an image (Hotspot Imager Service) and hardware (Kiwix Hotspots).
