Those users who have previously encountered DjVu format files know quite well that to open this extension, special software tools are required, which are often not available on a regular user's PC. A convenient alternative to the above inpatient programs will be used network resources, allowing you to both open DjVu online and convert it into another, easy-to-use format. Below I will talk about such online tools and also explain in detail how to use them.
DjVu format, developed by AT&T Labs, designed for storing scanned images (similar to the popular pdf). Since a djvu file can contain compressed, high-quality color images, photographs, text and drawings, it is quite often used for storing e-books, manuals, newspapers, old documents and so on.
There are a fairly small number of services on the network that allow you to open and view DjVu files. Working with such resources is extremely simple - you go to one of these services, upload your djvu file to it, select the quality of display of its contents (usually “high resolution” - i.e. “ a high resolution", and "low resolution" - i.e. “low resolution”), and view the result.
Insufficient number of network viewers to view files of this type can be compensated by the availability of a sufficient number of online converters that make it easy to transform a given file into a more convenient format for viewing (e.g. “pdf”).
Let's consider network tools that allow you to read the contents of a djvu file online.

Quite often, users who are accustomed to working with text documents on a computer or others electronic devices, may encounter the fact that some textbook or document is only available in DjVu format, and not all devices are able to read this format, and you won’t always find programs to open it.
There are many different converters that can help the user convert DjVu to the more popular text data format - PDF. The problem is that many of them do not help at all or do required action only under certain conditions and with maximum data loss. But there are several methods that have been appreciated by many users.
Method 1: Universal Document Converter
UDC Converter is the most popular program in order to convert a document from one format to another. It is with its help that you can quickly convert DjVu to PDF.
Converting a file through the UDC program takes a little longer than through other converters, but here you can choose Extra options and different output characteristics.
Method 2: Adobe Reader Printer
The Adobe Reader program, which allows you to view PDF documents, will also help you convert a DjVu file to this format. This is done in the same way as in the first method, only a little faster. The main thing is that the Pro version of the program is installed on your computer.
All other methods that will be indicated in the article are performed according to the same algorithm, but it’s still worth looking at them to understand what each program is.
Method 3: Bullzip PDF Printer
Another converter that is somewhat similar to UDC, but helps convert documents into only one format - PDF. The program does not have a large number of settings; you can only select those that are installed as standard. But the converter has one big advantage: the size of the document ultimately remains almost unchanged, and the quality remains at the best level.
Method 4: Microsoft Print
The last method uses a standard Microsoft printer that comes pre-installed on the system. It can be used when a document just needs to be quickly converted to PDF format without any deep settings.
The standard printer is very similar to the Bullzip PDF Printer program, so its algorithm of actions is the same, you just need to select it from the list of printers "Microsoft Print to PDF".
How to convert a DjVu file to a PDF file using a program? Users often encounter this problem when they need to get a PDF file from a DjVu file.
A file saved in the DjVu format (“deja vu”), in contrast to a similar file in PDF format, is significantly smaller in size. Therefore, technical literature, encyclopedias, dictionaries, etc., and other documents containing many images, diagrams, and photographs are often saved in the DjVu format. Book pages are saved in good quality, and the file itself will be significantly smaller than the same file in PDF format.
Why is there a need to convert DjVu to PDF? The point is that there is no a large number of programs created for viewing files in DjVu format. You can read about the most popular DjVu viewers in the “Text” section on my website.
Second important point, problem viewing DjVu format files on different devices. If there are no problems with viewing “déjà vu” on your computer, then on mobile devices this is more difficult. Even if there are appropriate applications, there may be problems with formatting, etc.

Therefore, a DjVu to PDF converter is needed. In order to convert DjVu to PDF, we use free programs for viewing DjVu format files (WinDjView, STDU Viewer, Sumatra PDF) that have a print function.

The Microsoft Print to PDF virtual printer is installed in the Windows 10 operating system, so users on this OS may not install such a program. On computers with operating systems Windows 7, Windows 8, Windows 8.1, you need to install a free virtual printer, for example, BullZip PDF Printer, PrimoPDF, CutePDF Writer, doPDF.
