Many ways to open djvu format both on a computer and on a phone

Recently, electronic books in the DjVu format have been very popular. Files in this format are generally smaller in size than PDF extension documents. The djvu format is widely used on the web. Many books, magazines on the Internet are contained in this format. However, PDF viewers do not support DjVu, which is why you have to work with two different programs at once.

The situation when it is impossible to view files with the djvu extension indicates that a program is not installed on the computer to view this format.

The use of this technology allows you to compress files of the same quality 3 times more compared to the PDF format. Another advantage of djvu is that viewing the document is possible as it is downloaded from the network – it is not necessary to wait until it is fully downloaded. Viewing djvu files is possible both with the help of plug-ins embedded in browsers, as well as stand-alone programs.
