Help => DjVu format and plugin   What is DjVu? DjVu is an electronic image format used to create and deliver text documents.  DjVu files are highly compressed and served using both client and server caching. Pages are streamed one at a time as they are requested, so documents are fast loading and the first page is available within seconds.   DjVu is similar to Adobe Acrobat's more widely recognized PDF format.  However,  DjVu delivers document images with higher quality and a much smaller file size.  This makes documents easier to store, distribute and view.  Click here for technical details of the DjVu format.
