About DjVu files

DjVu is a compressed file format that does not take up as much space as a high-resolution file format. The files are often hundreds of times smaller than files in high resolution formats.

Download DjVu program or plugin

When you click on a DjVu file, it opens in a DjVu plugin or in a program that can read DjVu. You need to download these to your computer.

PC

Download DjVu plugin for PC via Cuminas (new window).

Mac

If you have macOS, you can download download a free app that can read djvu files.

Do this:

  1. Go to the App Store.
  2. Search for DjVu.
  3. Choose an app and download.
