Offline Wiki

Introduction

This application saves and downloads a copy of nearly all of the textual content of the English Wikipedia locally so that it can be accessed without internet connectivity. It downloads and saves a compressed dump file and an index, 14MB for the small version and 1GB for the larger one (you can select which one from the settings). Using WebWorkers and the File API, it seeks to a specific part of the compressed dump, decompresses it with a pure javascript implementation of LZMA and renders the Wikitext as HTML. All of this happens almost instantly.

Install

You don't really need to, just bookmark this page and you can use it any time with or without internet access. If you want the convenience of getting to this from your new tab page, install the chrome app.
