What is DjVu?
Introduction to DjVu
DjVu is a an image format that can efficiently display images and textual materials that have been scanned into digital form. It is viewable through a browser plug-in in the same fashion as PDF files are with the Adobe Acrobat browser plug-in, see the next section for further information on getting the plug-in for your computer. If you are interested in more information about DjVu visit the DjVu Zone. In particular visit the introduction entitled What is DjVu? to gain a basic understanding of DjVu technology.
Downloading the Browser Plug-in
The DjVu browser plug-in is available for free for all the major computing platforms.
Click on one of the following Icons to begin downloading the plug-in for your machine:
Installing the Plug-in
Note: The information in this section is for Windows and Macintosh users only.
Download Speed: The size of the installation files for the DjVu plug-in is quite small, much smaller than the comparable Adobe Acrobat Plug-in for PDF files, so you shouldn't have to wait to long for download. The plug-in is provided freely by the Lizard Tech Company.
Windows users can generally be divided into two camps: (1) those that use Internet Explorer exclusively and (2) those that use, at least for part of the time, a browser other than Internet Explorer. Once you've clicked on the Windows download link on the the LizardTech download page that you will be taken to after clicking on the Windows/Mac download icon above, you will have two installation choices presented to you:
- Manual install
If you fall into the Internet Explorer camp you should choose the first option, Auto-Install. This is the fastest installation option. Once you accept the license the plug-in will automatically be downloaded, installed, and integrated with Internet Explorer.
If you use a browser on Windows other than Internet Explorer you should choose the second option, manual install. This option will allow you to choose which browsers, including Internet Explorer, the DjVu plug-in will be configured to work with.
Choose the appropriate download link for your Mac OS and follow the standard installation procedure for installing applications that come bundled in .hqx file for your Macintosh platform.
Using the DjVu Plug-in
Once you've installed the DjVu plug-in any link that points to a DjVu file should launch the plug-in and show you the document within your browser.
