Djvu does not open files. How to open a djvu file on a computer

Many e-books have the extension .djvu. This format is especially popular for books on educational and scientific topics due to the high compression of documents, often several times higher than in .pdf. Let's find out what this format is, how to open a .djvu file, what applications can be used to read such books on a computer and mobile devices Oh.

About this extension

Before we consider how to open djvu-format files, let's understand what it is. In fact, these are scanned copies of document pages collected in convenient packaging. The .pdf format is often used for the same purpose, which can cause confusion. There are differences, since .pdf can also contain plain text, which allows, in particular, copying.

The .DjVu format was developed at the end of the last century in the AT&T laboratory and sold to LizardTech. To achieve high compression of high-quality images, it uses special technologies (for example, layering). The compression ratio of color documents in .DjVu is 5-10 times higher than in .jpeg, and 3-8 times higher than in .tiff compression.

DjVu is read as dejavu (deja vu). Files in this format have the extension .djvu. They are generated by special programs such as DjVuLibre or DjVuSmall and may contain tables of contents and links. This makes it easier to navigate when viewing documents.

2 ways to read .djvu on a computer

There are two ways to work with this format. First, a program that opens .djvu files must be installed. And the second is the use of a converter, with the help of which you can convert them into another format, for example.fb2 or.pdf.

Computer reading programs

Let's consider which program to open the .djvu file. Perhaps the most popular of them is DJVU Reader. It is distributed freely on the Internet. The downloaded archive must be unpacked into a separate folder, using, for example, the WinRAR archiver. Select the “Extract to specified folder” option from the drop-down menu when you right-click on a folder in the archive. Next, open the folder where you placed the program, find the DjVuReader.exe object, right-click on it and select “Create shortcut”. Then you need to drag this shortcut to the desktop and rename it as you wish. The program is installed on the computer.

Usage: you need to open it using the created shortcut - a blank gray sheet will open. The only available control on the menu is the File button. Click on it, select the “Open” option in the drop-down menu and in the dialog box - a file of the .djvu type for viewing. After loading the book, you can change the image scale (using the “+” and “-” buttons), turn pages (using the “Forward” and “Back” arrows), go to specific pages of the document, copy text or image.

Another famous program, which allows you to solve the problem of “how to open a .djvu file” is WinDjView, which works in most versions of Windows. It allows you to open books, read text continuously, insert bookmarks, search for phrases in a document, select and copy text or a picture, and perform other actions with files. Some actions are only available if the document has an embedded text layer. The advantage of the program is that it is almost weightless and fast program viewing books like .djvu with continuous scrolling of pages and additional features print.

You can also use the free programs DJVUView and STDUViewer. They can be downloaded from official websites.

Naturally, there are other programs that have slightly less functionality.

Online reading.djvu on the computer

Without installing special programs, you can read documents of the format in question using the special DJVU BrowserPlug-in plugin, supported by almost all popular browsers. By downloading and installing it on your computer, you can read .djvu files directly from the Internet. When installing, you must specify the OS version, latest version and plugin language.

How to read .djvu on MAC OS?

Fans of Apple computers are also interested in the question of how to open a .djvu file. To do this, try DjVuReader, which you can find on the AppStore. It is paid, but much more convenient than the others, since it has the ability to display pages in two columns, switch between scrolling modes and continuous scrolling of pages, supports working in full screen, can rotate individual pages in any direction, select any section of the document and copy it to the clipboard. Export to .pdf format without conversion quality settings is also supported.

To read djvu files on Mac OS, you can also use the DjVuLibre or MacDjView applications - a simple program with continuous page scrolling and the ability to flip the document on its side. The DjView program, which works quickly, allows you to read such files, allows you to display them in two columns, scroll continuously and search through the document. It is possible to customize the program interface to your requirements and export the entire document or several of its pages from .djvu to other formats (.pdf, .jpg, .tiff, etc.) with setting the compression level and image resolution.

How to open it on Android?

The following applications will allow you to open the .djvu file on Android:

1. VuDroid is a freely distributed English-language program.
2. DJVUDroid - also free program, which, in addition to reading, allows you to open recently viewed documents and search for them inside folders.
3. EBookDroid is a freely distributed application for reading not only .djvu files, but also .pdf.
4. CoolReader, which supports viewing not only .djvu, but also .fb2, .pdf and a number of other “book” formats.
5. OrionViewer is an e-reader that supports bookmarks, tap zones, overriding hardware keys, works unusually fast, has settings for turning pages and cropping fields, allowing you to read not only .djvu and .pdf, but also exotics (such as .xps and .cbz) .
6. DjVureader for Android - fast, quickly opens very large files, different high quality image reproduction, has Personal settings, which will help give the reader a unique look and optimize it for each mobile device user.

There are also a number free applications for reading.djvu. All of them have limited functionality compared to paid applications. In particular, they do not provide the ability to edit such files; they often lack the ability to search, select and copy text and pictures.

For installation the desired program Enter its name into the search bar of your device's app store. In the search results, find the application you are looking for and install it as you usually install programs on your device.

Converter.djvu to.pdf

Let's say there is no possibility or desire to install a program that allows you to service the .djvu file extension. How to open such books in this case? You should convert the file to another “book” format. There are no sufficiently powerful .djvu to .fb2 converters yet. The existing ones take a very long time to translate books of more than 500 pages. Therefore, we will consider the more successful available .djvu to .pdf converters.

First we download special program DJView. Next, tear off the archive and run boot file. Installation is carried out using a simple wizard and does not cause problems. After installation, launch the application using an automatically generated shortcut on the desktop.

To convert .djvu to .pdf, download the book in .djvu format through the “File” - “Open” menu. We carry out the conversion through the menu “File” - “Export ...”, selecting the position “ in the “Result” - “Format” panel PDF document" We confirm the operation (“OK”) and wait for the conversion to complete, which does not last long. As a result, a document in .pdf format will appear in the destination folder.

In addition, to convert .djvu to .pdf you can use free online service docspal. After calling the domain of the same name in segment.com and selecting the file to convert (or specifying the link), click the Convert button. Conversion occurs automatically at a speed depending on the size of the file and the quality of the Internet connection. A link to the resulting file appears in the Converted files field, which can be opened with your existing .pdf viewer.

conclusions

There is nothing complicated about how to open a .djvu file! There is a way out even if it is impossible to install a special viewing program.

Good day!

I'm pretty sure they're amateurs e-books We've already encountered this format dozens of times - DjVu (even its spelling is somewhat unusual?).

It has a unique feature: the degree of compression of the scanned document in it (and indeed any pictures) is superior to all competitors (surprisingly, it is higher than that of). Thanks to this, even the largest book can be placed in a compact file and transferred over the network.

However, due to the specificity of the format, it is not possible to open it in every program (and even after opening it, it is not so convenient to read and use the document in many readers). In this article I will recommend several irreplaceable programs that open 99.99% of DjVu files, display them correctly, and allow you to work with them comfortably.

Note:The article provides programs for Windows. If you need an e-reader for Android, I recommend choosing something universal, for example, these products:

For reading (readers)

WinDjView is one of the fastest and most compact programs for viewing this format. It is very convenient that it implements continuous scrolling of pages; on the left there is a panel for quickly moving through the document (contents).

I will also note the presence of an advanced printing function (allows you to customize the printout in a way that cannot be done in similar software). The program is based on the freely distributed DjVuLibre library.

Peculiarities:

• the ability to open multiple documents at once (using tabs, like a browser);
• the presence of a full-screen version (makes the document easier to read);
• ability to create bookmarks;
• the ability to adjust contrast, brightness, color scheme, etc. for a comfortable pastime;
• export page to image format (GIF, JPG and JPEG);
• support for Russian and all popular versions of Windows 7, 8, 10.

A very convenient and compact program for viewing all popular e-book formats: PDF, DjVu, ePub, MOBI, XPS, CHM, CBZ and CBR. Together with a minimalist style interface, low system requirements and ease of use - make it one of the favorite products of millions of users around the world!

In addition, Sumatra PDF is completely free, consumes less memory than many analogues (for example, Adobe Reader), does not require installation (can be carried with you on a flash drive), supports hot keys, display settings, etc.

Of the minuses: there may be some problems when opening old DjVu files (apparently, after all, you won’t be able to do without a standard DjVu reader...).

Despite the fact that this program has not been updated for a long time, it copes with its task perfectly! Its main advantages:

• support for almost any DjVu files;
• the presence of a side menu with contents, thumbnails, etc. - allows you to quickly navigate through the document;
• adjusting image brightness and contrast;
• low PC requirements: especially noticeable when opening large files on weak machines;
• Convenient navigation using the keyboard (you don’t have to use the mouse at all!)
• small size, no need for installation;
• Russian support, Windows support XP, 7, 8, 10.

Of the minuses (purely in my opinion): there is no smooth scrolling of pages (I’m very used to this).

To create DjVu (encoding/decoding)

DjVu Small

Website: http://www.djvu-soft.narod.ru/scan/djvu_small.htm

This is one of the most simple programs For DjVu creation-files (from ordinary pictures that everyone is used to working with: TIF, JPG, BMP, GIF and PNG). The program is very convenient, universal, works on almost all Windows 98/NT/XP/7/8/10 operating systems.

I note that the program can compress one or more images in DjVu (this is called coding ), and unclench (i.e. decode - get/extract pictures from DjVu).

The program does not require installation. Supports Russian interface.

To compress images in DjVu you need (see screenshot above):

1. open folder or files;
2. select the folder where the received file will be saved;
3. select quality (here it is quite difficult to give a specific recommendation, because you need to choose based on the original quality. To begin with, I recommend choosing the “Default” option; if the quality/file size is not satisfactory, change it to an excellent option);
4. Click the "Start" button.

DjVu DocExpress

Website: http://www.djvu-soft.narod.ru/soft/

A very powerful program for creating and editing DjVu documents. For example, the program can turn all pages at once by 90-80 degrees, create links to pages within a file or to individual pages on the Internet.

As for creating a DjVu file in it, everything is simple:

PdfToDjvuGUI

Website: http://www.trustfm.net/software/utilities/PdfToDjvuGUI.php

One of the simplest solutions is PdfToDjvuGUI. The point is that you can create DjVu not from pictures (as in previous versions), but from PDF file. In some cases this is much more convenient and faster.

After starting the program, just select the file (the "Add PDF" button), and then click on the "Generate DjVu" button (if necessary, set the compression settings).

Then automatic file conversion will start (just wait until the “black” window is closed). The DjVu file will be created in the same directory in which the PDF added for conversion was located.

Online conversion services

Now there are quite a lot of services on the network that offer to upload a file to them and quickly convert it to DjVu. Of course, they can hardly be used for scanned documents (after all, they often contain personal and corporate information). But as an example, here are a couple of options:

• - the service allows you to quickly convert PDF to DjVu (the file should not exceed 100 MB);
• - another service (its arsenal has quite a lot of conversion directions). Using the link given above, you will find the opposite option: DjVu to PDF.

That's all, good luck!
