How to create a file djvu

1) djvu small

A program for creating a DJVU file from the PMP, JPG, GIF format pictures, etc. By the way, the program can not only create, but also to extract from DJVU all graphic files that are in compressed format.

It is very easy to use her. After starting the program, you will see a small window in which you can create a DJVU file for several steps.

1. To begin with, press the Open Files button (red one on the screen below) and choose those pictures you want to take into this format.

2. The second step is to choose a place where the created file will be saved.

3. Choose what to do with your files. Document -\u003e Djvu - It is to convert documents to DJVU format; DJVU Decoding - This item needs to choose when you instead of pictures in the first tab select the DJVU file to extract it and get its contents.

4. Select Encoding Profile - Selection of compression quality. The best option There will be an experiment: take a couple of pictures and try to squeeze them if the quality arranges you - then you can then compress the entire book with the same settings. If not - then try to increase the quality. DPI - this is the number of points, the higher this value - the better qualityAnd the more the size of the source file is obtained.

5. Convert. - Button that runs the creation of a compressed DJVU file. Time for this operation will depend on the number of pictures, their quality, PC power, etc. 5-6 pictures went about 1-2 seconds. On average, the power of the computer today. By the way, below shows the screenshot: the file size turned out to be approximately 24 KB. From 1MB source data. It is not difficult to calculate that the files were compressed in 43 * times!

Another good program to create and extract DJVU files. Many users it seems not as comfortable and visual as DJVU Small, but still consider the process of creating a file and in it.
1. Open the pictures that you scanned, downloaded, took from friends, etc. Important! First, open only 1 picture from all the desired convert!
Important moment!Many cannot open pictures in this program, because By default, it opens DJVU format files. To open other graphic files, simply put in column file types value as in the bottom of the bottom.
2. After your one picture has been opened, you can add the rest. To do this, in the left program window you will see a column with a small preview of your picture. Right-click on it and select "INSERT PAGE After" to add pages (pictures) after this.
Then allocate all the pictures you want to compress and add to the program.
3. Now click on File / Encode AS DJVU - Coding in DJVU.
In the next step, you are asked to specify the place where the encoded file will be saved. By default, you are offered a folder for saving the one from which you add the files of the pictures. You can choose it.
Now you need to choose the quality with which the program will freeze the pictures. It is best to choose it experimentally (because many tastes are different and the specific numbers are useless). Just leave first by default, squeeze the files - then check whether you will arrange the quality of the document. If it does not suit, then then increase / reduce quality and check again, etc. Until you find your balance between the size of the file and its quality.
Files in the example were compressed to 28kb! Pretty well, especially for those who want to save space on the disk, or those who have a slow Internet.

Good day!

I am almost sure that lovers electronic books Already dozens of times met with this format - djvu (even his writing is somewhat unusual?).

He possesses unique feature: The compression ratio of the scanned document in it (and indeed any pictures) - exceeds all competitors (surprising, but it is higher than that). Because, even the largest book can be placed in a compact file and transfer it over the network.

However, due to the specificity of the format, it is not possible to open it in every program (and opening it, in many reeers to read and use the document is not so comfortable). In this article, I will recommend several essential programs that open 99.99% of DJVU files, they are displayed correctly, and allow you to work comfortably with them.

Note: The article provides Windows programs. If you need a 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 the continuous scrolling of pages is implemented in it, the shortest displacement panel is provided on the left (content).

I also note the presence of an extended printing function (allows you to configure the printout as you can not be made in a similar software). The program is based on the free DJVulibre library.

Features:

the ability to open several documents at once (using tabs, like a browser);
the presence of a full-screen version (facilitates the reading of the document);
the ability to create bookmarks;
the ability to adjust contrast, brightness, color gamut, etc. for a comfortable pastime;

In addition, Sumatra PDF is completely free, consumes less memory than many analogs (let's say Adobe Reader.), does not require installation (you can carry with you on the flash drive), supports hotkeys, mapping configuration, etc.

Of the minuses: there may be some problems when opening old DJVU files (apparently, still, without a regular DJVU reader, you can not cost ...).

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

support for almost any DJVU files;
availability side menu With content, sketches, etc. - allows you to quickly move according to the document;
setting the brightness and contrast of the image;
low requirements for PC: especially noticeable when opening large files on weak machines;
convenient navigation with the keyboard (you can not use the mouse at all!)
small size, no need for installation;
support for Russian, support for Windows XP, 7, 8, 10.

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

To create DJVU (encoding / decoding)

Djvu Small

This is one of the most simple programs To create DJVU files (from ordinary pictures with which everyone used to work: TIF, JPG, BMP, GIF and PNG). The program is very convenient, universal, works in almost all Windows 98 / NT / XP / 7/8/10.

The program does not need installation. Supports the Russian interface.

To compress pictures in DJVU, it is necessary (see screen above):

open folder or files;
select a folder where the file received will be saved;

press the Start button.

Djvu docExpress.

Then to start automatic conversion of the file (just wait until the "black" window will be closed). The DJVU file will be created in the same directory in which the PDF is added to the conversion.

Online Conversion Services

Now the network is quite a lot of services offering downloading a file to them and quickly convert it to DJVU. Of course, they can hardly be used for scanned documents (nevertheless, they often contain personal and corporate information). But for example, I will give a couple of options:

- the service allows you to quickly overtake PDF in DJVU (the file should not exceed 100 MB);
- Another service (in his arsenal there are quite many conversion directions). By reference, which led to, you will find the reverse version: DJVU to PDF.
