Convert djvu file to pdf. How to convert a DJVU file to PDF (read convert redo conversion)

With development electronic document management and an increase in the number of office users, an enterprise often faces the question of standardizing the formats used in the institution. It is especially difficult in this sense for various kinds of universities and colleges, in which a lot of scanned scientific literature is stored in the form of DJVU.

Of course, this format was specially created for these purposes, but its prevalence leaves much to be desired. In any case, it would be better to convert DJVU to PDF. This will allow you to use in everyday work much simpler and more common programs that are already installed on the computers of most users.

What format is this?

In order for you to understand the need for such conversion, it is worth learning a little about the format itself, which is the “stumbling block”. As mentioned above, it was created for the digitization of books and scientific aids. Its advantage is its impressive compactness.

But there is one caveat here: all this applies only to those cases where the quality of the output document is not particularly important. For example, you can easily digitize and use in the future those manuals that contain a lot of images and high-quality tables.

What causes poor quality?

But much more often you see digitized documents of terrible quality, in which it is almost impossible to make out anything. What is this connected with? The thing is that in the DJVU format there are no fonts in the documents. In fact, such a document is a kind of “advanced” image.

So converting DJVU to PDF will allow you to at least somehow improve the readability of books that have been half-heartedly transferred to digital format.

How to convert?

A universal, simple and extremely compact program - DjView. It will allow you to convert even a large document in just a few minutes. The downside is that you can't select PDF specifications. What specific type of format is used for conversion at any given moment is unknown.

Virtual printer

This method will allow you not only to convert DJVU to PDF, but also to save even a web page in the format you require. How to convert in this case? First, you should install novaPDF or a similar program. To directly open the document we will use the WinDjView utility.

Once installed and configured, you can open DJVU books. PDF is obtained after you send them for “printing”. Unlike the previous case, you will be able to configure all parameters of the output document. Conversion time depends entirely on the characteristics of your computer, but about a hundred pages are converted in 10 minutes.

FineReader

This application should be well known to domestic users, since for a long time it was the only option for quality. Today the program is already in its twelfth version, and its functionality has been radically expanded.

To convert DJVU to PDF, you must first launch the application. A main window will appear in which you should select the “Image file to PDF” option. Will open special utility, where the program needs to specify the path to the file that needs to be converted into a format more familiar to you.

But there is one problem. Firstly, the application is paid. Secondly, its performance drops with the release of each new version. If your computer does not shine with performance, then the DJVU book of 200-300 pages can “hang” it tightly.

Therefore, on weak machines and if the document is relatively small, it is better to use the utility included in the same FineReader. It's about about Screenshot Reader. The principle of its operation is to recognize text from page snapshots that the program takes independently. It consumes a minimum of resources, and the results are excellent.

STDU Converter

This utility will easily convert DJVU to PDF without spending a lot of time on this process. Its advantage over competitors is not only that it is free, but also that it has functionality that is quite comparable to them. Yes, you can convert to required format not the entire document, but only some fragment of it, by marking the corresponding pages with checkboxes.

The simplest option

The downside to all of the above applications is the fact that they are quite complex, and therefore may not be so easy for beginners to understand. The Boxoft application may be a way out of this situation. Its interface is as simple as possible. To convert, simply drag the document icon into the main program window, after which a similar file will appear in the same folder, but in PDF format.

When should you not convert?

We have already said what the advantage of DJVU is. In the case where the document has acceptable quality, and you are going to use it on a mobile device or through cloud service, there is no reason to redo it.

There are 3 main ways to convert DjVu files to PDF format- using a converter on a computer, through printing on a virtual printer of the operating system and using online services. Let's look at each conversion method in more detail and choose which one is faster and more convenient.

Method 1 - converter utility

Suitable for Windows OS users only. Download the DjVu to PDF converter. Unpack the downloaded archive to the root of any hard drive on the computer. Open the program folder, find and run the file called “Djvu Small Mod.exe”.

In the window that appears, in the middle, find and select the “Decode DjVu” operation.

After this, the interface will change a little, click the “Open file(s)” button at the top. Select one or more DjVu files that you are going to convert (batch conversion is supported).

In the decoding options, where it says "Output Format", click on the drop-down list and select PDF (see screenshot).

Then click the Browse button and select the folder where the created file will be saved.

At this point the preparations are completed. To convert selected DjVu files to PDF format, click on the right big button"Decode". The conversion happens page by page, so you may have to wait a minute or two, depending on the size of the files being processed.

Advantages of the method: no internet required, no advertising, independence from operating system components, confidentiality, simplicity, batch conversion, no installation required, small size generated PDF file, high speed.

Minuses: could not be identified.

Method 2 - through the WinDjView program (virtual printing to file)

Drag the DjVu file onto the site page or click on the red button and select it from a folder on your computer.

Then click the “Convert” button and wait until the green “Download” button appears.

After the process is completed, download the finished file; you can also compress it before doing this.

The service also supports saving the result in Google Drive and Dropbox.

Advantages of the method: no need to download the program, suitable for users of any OS (Windows, Mac OS, Linux, Android, etc.).

Minuses: a permanent Internet connection is required, you will have to look at advertisements on the site, the Internet speed should be enough to send and download a file; converts slower than computer programs; third parties will know which books you are converting; Sometimes there are problems with the encoding - scribbles are displayed instead of Cyrillic.

Having summarized the pros and cons of the three methods, we conclude that it is more convenient to convert DjVu to PDF through a converter. Do you agree? Answer in the comments.
