OpenZIM

ZIM is a perfect suited file format to store Wikipedia on a USB stick

The openZIM project proposes offline storage solutions for content coming from the Web. The project has two different targets:

• Definition of the ZIM file format: an open and standardized file format,
• Implementation of the zimlib: an open source (GPLv2) implementation of the ZIM file format.

See our mission statement for more details

The openZIM project was launched by Wikimedia CH (Switzerland) and is actively supported by the Wikimedia Foundation.
