Doesn't read pdf format. PDF Readers

Despite the fact that viewing PDF documents and books on the desktop platform is not difficult, many users still have a question about how to open a pdf file.

In this guide, I will list several pdf viewers - perhaps the best on this moment. If you need a reader for your phone, refer to.

pdf viewers participating in the review:

Adobe Reader is the most famous PDF reader.

Developer: Adobe Systems Incorporated
Distribution terms: freeware

Not a fact, the inventors of any document format can write an ideal program for opening PDF. And even knowing all the "secrets" does not help. We hasten to dissuade: in the case of Adobe Reader - the most famous program for working with PDF - this is not so.

Don't know how to open pdf file? Adobe Reader is the first thing that comes to mind

In the current version, the program is distributed under number 8. When downloading the distribution, do not confuse it with Adobe Acrobat (without the "Reader" prefix), which, in addition to viewing, includes PDF editing tools. Although it is difficult to confuse, since the second package is close to 0.5GB in size. Adobe Reader occupies 22 MB, Current version is numbered 8.1.2 and is available at the above address. On this page, you need to select the language and operating system for which you are downloading the program. This once again confirms the "universalism" of the PDF format.

The first thing that catches your eye when you open such a viewer program is the interface. Also, as in other Adobe products, it is very stylish and, more importantly, thoughtful. And from version to version there is a movement in better side. What is this convenience? The fact that when you open a document, you do not have to look for a particular button for a long time. The most frequent actions are performed with one or two mouse clicks. Sidebars and tools are mostly "legacy" from previous versions of Reader (then still with the prefix "Acrobat").

Reader has more settings than other viewers, which is understandable: who, if not Adobe, knows the "secrets" of the PDF format. However, many options, such as 2D and 3D settings, disappear as unnecessary. These technologies are still rarely used in PDF files. Another conditional group of settings is the possibility of displaying a document on the screen. These are: font smoothing, headset settings, output control (!) to different monitors.

An important advantage of the Adobe Reader package is that it is free. Flaw - slow work on some average computer. Most important parameter here - the frequency of the processor, since during viewing it is the most loaded. And, since the document may be replete with high-resolution images, it is not certain that you will be able to fully use the program.

The slow work of Adobe Reader lies not only in the incorrect settings of the program, but also in the presence of additional functions. All plug-ins are enabled by default. They cannot be disabled by standard methods, so you will have to resort to the help of a special PDF SpeedUp tweaker program, which will be discussed later.

Short description: pdf viewer software

For the Windows platform, there are not so many programs for viewing pdf documents. First of all, Acrobat Reader specializes in this. Unfortunately, from version to version, the program does not at all become more compact, but acquires additional features, which only slow down the browsing speed.

Sumatra PDF is a viewer for users who value conciseness. First of all, let's pay attention to the size of Sumatra PDF - less than a megabyte. Secondly, there are no plug-ins and no need, since everything for viewing PDF is already there. Sumatra PDF also has no settings. Therefore, Sumatra does not support font smoothing technology and other conveniences.

Distribution terms: freeware

To view and print files in PDF, Adobe Reader is more than enough. But if the speed of the program is important to you, install its most famous alternative - Foxit Reader.

Foxit Reader - PDF viewer

Page output speed in Foxit Reader is characterized by surprisingly fast page opening. No need to wait for the next page to appear for several seconds. If in Adobe Reader "clumsiness" appears when scrolling pages and opening thumbnails, but this is not observed here. Foxit Reader does not support plugins, functionality is enough without it.

Watching the development of the program, one could notice its gradual improvement compared to previous versions. Basically, the interface has changed: it has become more convenient, in this regard, it even got closer to the Reader (compare at least the panels in one and the other reader). As in a browser, the system of tabs is organized, which is convenient when viewing several documents in one window. However, this is not some kind of innovation, but the most standard for a program of this kind.

There are fewer settings in Foxit Reader than in Reader, but the most important ones are still present. For owners of LCD monitors, a very useful option "Display text optimized for LCD screen" is provided, which saves fonts from unpleasant roughness.

About the shortcomings. It has been noticed that sometimes when minimizing / maximizing the Foxit Reader window, the toolbar gets lost and spreads almost half the window. The program has to be restarted. Also, sometimes there are problems with highlighting text in a document: text lines are distorted, you need to update the page unscheduled.

Initially, the program has an English interface, you can Russify it via the Internet.

Finally, it is worth mentioning that Foxit Reader is also available on Android, among other pdf viewers.

Of course, STDU Viewer has all the basic functions that a viewer must have when reading pdf. First of all, it is worth mentioning changing the size of text, rotating the page of a document, changing the brightness and background of pages, quickly printing a document or selected fragments.

If the document has a text layer, you can open pdf file, highlight text, copy it to the clipboard, or export it to another text format.

Two editions of the PDF viewer are available on the website of the STDU Viewer developer: standard and portable.
