Kiwix Android

Kiwix is an offline reader for Web content. One of its main purposes is to make Wikipedia available offline. This is achieved by reading the content of a file in the ZIM format, a highly compressed open format with additional metadata.

This is the version for Android, with support versions ranging from 7.1 to 13.

Important Note: Starting from Android 11, the ZIM file picker feature has been restricted in the Play Store variant due to Play Store policies. This means that users running Android 11 and above will not be able to load ZIM files from internal/external storage directly within the app if they have downloaded Kiwix from the Google Play Store. This restriction is in place to comply with the Play Store policies. The Play Store variant of Kiwix does not require the MANAGE_EXTERNAL_STORAGE permission anymore, which is necessary to scan storage and access ZIM files at arbitrary locations. Therefore, the storage scanning & file picking functionalities are not available in this variant anymore. For already downloaded ZIM files, You can copy them to the Android/media/org.kiwix.kiwixmobile/ folder, and the application will read them. Before uninstalling the application, please ensure that you move all your ZIM files from this folder, as they will be automatically deleted when the application is uninstalled or if the application data is cleared. To use the full version of Kiwix and benefit of the ZIM file picker feature, you can download it directly from the official repository or use F-Droid. We understand that this restriction may cause inconvenience, but it is necessary to comply with the Play Store policies and ensure a smooth user experience. We recommend using the official version of the app available on our website to access the complete set of features.
