In a nutshell
Offline & Ad-free
Kiwix Reader is a web-browser-like application designed to open and display ZIM files—highly compressed archives of online resources. It is ad-free and we commit ourselves in keeping it so forever.
Wikipedia
Kiwix was originally developed to make Wikipedia—the world’s largest free knowledge resource—available offline. Over time, Kiwix has evolved into a versatile offline solution that supports a wide range of content. Despite this expansion, Wikipedia and related Wikimedia projects remain the most popular and prominent resources accessed through Kiwix.
Free & Open source
Kiwix is not just free to use but also a Free Software (sometimes incorrectly named “Open Source”). This is essential for security and maintainability over time.
Multi-platform
Via the Kiwix Reader, you can access your offline content on Windows, macOS, Linux, Android, iOS and even on any platform with a web-browser via our Kiwix Server (Linux, macOS, FreeBSD, Windows) or a Kiwix Hotspot.
Your pocket library
Browse the online catalog of ZIM files and download your favorites directly within the app, instantly turning your device into a local hotspot. Share your ZIM library across your network without needing an internet connection and separately from the Kiwix Hotspot, effortlessly bringing offline knowledge to everyone around you!
