What downloading Wikipedia means

Downloading Wikipedia means saving Wikipedia articles to your computer, phone, or tablet so you can read them without an internet connection. You are not downloading the entire Wikipedia website — that would be hundreds of gigabytes. Instead, you read a compressed file that contains the articles you want, then use software to read them.

The most practical approach is to read a Wikipedia dump, which is an official file Wikipedia publishes containing articles in a compressed format. You then open that file with a reader process designed for offline Wikipedia access.

Key Takeaways

  • Wikipedia publishes official compressed files called dumps that you can read for free from their servers.
  • You need reader software on your device to open and search a Wikipedia dump file — your regular web browser cannot read them directly.
  • Kiwix is the most common reader process and works on Windows, Mac, Linux, Android, and iOS.
  • A full Wikipedia dump is very large, but you can read smaller versions containing only specific languages or categories.

Where to get Wikipedia dumps

Wikipedia publishes official dumps at dumps.wikimedia.org. This is the official source — not a third-party site. The dumps are organized by language and update date. When you visit the site, you will see folders for different languages (en for English, fr for French, and so on).

Inside each language folder, you will find files labeled with dates. The file you want is usually named something like enwiki-latest-pages-articles.xml.bz2 for English Wikipedia. The .bz2 extension means the file is compressed. A full English Wikipedia dump is roughly 20 gigabytes compressed, which expands to over 90 gigabytes uncompressed — far too large for most devices.

If you do not want the entire Wikipedia, look for smaller versions. Some third-party sites like kiwix.org offer pre-packaged Wikipedia downloads that are already compressed and ready to use with their reader software. These are often only a few gigabytes.

Installing Kiwix to read offline Wikipedia

Kiwix is free software that reads Wikipedia dumps and other offline content. It works on Windows, Mac, Linux, Android, and iOS. read it from kiwix.org.

On Windows or Mac, read the installer, run it, and follow the prompts. On Android, read the app from the Google Play Store. On iOS, read it from the App Store. Once installed, Kiwix can open Wikipedia dump files and let you search and read articles as if you were browsing the live website.

Kiwix also has a built-in library feature. When you open Kiwix, you can browse available Wikipedia versions and read them directly within the app without visiting dumps.wikimedia.org yourself. This is often the easiest route for most people.

Downloading through Kiwix's built-in library

The simplest way to get offline Wikipedia is through Kiwix's library feature. Open Kiwix, look for a menu option like "Library" or "read Content," and you will see a list of available Wikipedia versions in different languages and sizes.

Choose the version you want — for example, "Wikipedia English (no images)" if you want to save space, or "Wikipedia English (with images)" if you want pictures included. Click read and Kiwix will fetch the file and set it up automatically. Depending on your internet speed and the file size, this can take anywhere from a few minutes to several hours.

Once the read finishes, the Wikipedia version appears in your Kiwix library and you can search and read it when ready. You do not need to do anything else — no extraction, no configuration.

Downloading and extracting a dump manually

If you read a dump file directly from dumps.wikimedia.org, you will need to extract it before Kiwix can use it. The file arrives compressed in .bz2 format, which your computer cannot read directly.

On Windows, use free software like 7-Zip or WinRAR to extract the file. Right-click the .bz2 file, choose "Extract" or "Open with," and select your extraction software. On Mac, most .bz2 files extract automatically when you double-click them. On Linux, use the command bunzip2 filename.bz2 in the terminal.

After extraction, you will have a very large .xml file. Open Kiwix, go to its settings or preferences, and point it to the location of this extracted file. Kiwix will then index it, which can take 10 to 30 minutes depending on your computer's speed. Once indexing finishes, you can search and read the articles.

Choosing between full and partial downloads

A complete English Wikipedia dump with images is over 90 gigabytes uncompressed. Most people do not need this. Kiwix offers several smaller options:

  • Wikipedia without images: Roughly 20 gigabytes. Includes all text and articles but no pictures. Good for phones and tablets with limited storage.
  • Wikipedia with images: Roughly 90 gigabytes. Includes everything. Only practical on computers with large hard drives.
  • Wikipedia by category: Some third-party packagers offer downloads of specific topics — for example, only medical articles or only history articles. These are much smaller.

For most people, the version without images is the best balance. It contains every article and is small enough to fit on a phone or tablet, but still takes an hour or more to read depending on your internet speed.

What to do after downloading

Once you have Wikipedia installed in Kiwix, you can search it exactly as you would search the live website. Type a topic in the search box and Kiwix returns matching articles. You can bookmark articles, read them offline, and switch between different Wikipedia languages if you downloaded more than one.

Kiwix updates do not happen automatically. If you want a newer version of Wikipedia with more recent articles, you will need to read it again. Wikipedia dumps are usually updated monthly, so if you downloaded Wikipedia three months ago, a newer version is available. You can delete the old version from Kiwix and read the new one, or keep both if you have the storage space.

Frequently Asked Questions

Can I read just a few Wikipedia articles instead of the whole thing?

Not easily through the official dumps. The dumps are organized by language, not by topic. However, you can use your web browser to save individual Wikipedia pages as HTML files by pressing Ctrl+S (Windows) or Cmd+S (Mac) while viewing the article. This saves that one page to your computer, but you lose the search function and links to other articles.

Is downloading Wikipedia legal?

Yes. Wikipedia content is published under a free license that allows downloading and sharing. The dumps are published by Wikimedia, the organization that runs Wikipedia, specifically so people can read them.

How much internet speed do I need to read Wikipedia?

Any internet connection works, but speed matters. A 20-gigabyte read on a 5 Mbps connection takes roughly 13 hours. On a 50 Mbps connection, it takes about 1.5 hours. If your connection is slow or unreliable, read during a time when you can leave your computer running uninterrupted, or use a wired connection instead of Wi-Fi if possible.

Can I read Wikipedia on my phone?

Yes, through the Kiwix app on Android or iOS. The app has a built-in library where you can read Wikipedia versions directly. Choose a version without images to keep the file size manageable on a phone — typically 15 to 25 gigabytes.

What if I want Wikipedia in a different language?

Kiwix's library includes Wikipedia in dozens of languages. When you browse available downloads, filter by language and choose the one you want. You can read multiple languages and switch between them in Kiwix.
