OpenZIM

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.

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

See our mission statement for more details

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