How to view a pdf file on a computer. How to open a PDF file

PDF is an acronym for Portable Document Format. It was created by Adobe to represent various text and graphic information in this file. Typically, these files can only be viewed and printed, but some can also be edited using special programs.

PDF format usually contains information about goods and services; they can be instructions, a book with pictures. Some compare this format with the doc and docx format. Only it is heavier and, so to speak, a “magazine version”. Indeed, when you open this type of file, you seem to find yourself in a kind of magazine that is very pleasing to the eye.

Since Adobe created such a format, it means there must be a program that opens this file. It's called Adobe Acrobat Reader. It is best to download the program from the official website of the developer, because that is where the latest version of the program is always located.

Downloading and installing PDF readers

It's up to you to install it or not. The download and installation process takes about 10 minutes and proceeds in standard mode.

In addition to Adobe Reader, there are many third-party programs that also read and work with these files.

PDF is one of the most common formats for documentation, e-books and instructions. In PDF format, you can save information in any form, and it will be displayed the same everywhere, i.e. The formatting and layout of the document will always be the same. This is why the PDF format has earned its recognition.

To begin with, I would like to immediately clarify that the programs that will be discussed open PDF files only FOR VIEWING, i.e. It is IMPOSSIBLE to change anything in a document using them. Some programs only allow you to modify the text, but not the content. The PDF format itself is quite specific, and even with the help of editors, the process of editing it is not at all similar to working with a Word document.

In the simplest case, you can read the file in any modern browser: Google Chrome, Firefox, Opera, Internet Explorer, Edge. The functionality will be limited: only viewing content and printing. To do this, simply drag the file to an empty browser tab. But if the PDF file does not open this way, then try installing one of the programs.

Uncompromising Acrobat

In order not to have any problems with displaying PDF files, it is best to install the program of the format developer itself - Adobe Acrobat Reader.

Just select the program language “Russian” if the download page itself does not correctly determine it. The installation process is trivial, just click “Next” all the time.

Adobe has a complete package for working with PDF documents, including creating and editing - but it is paid.

Acrobat Reader provides a good range of features and customization flexibility for ease of use. It's completely free for both home and commercial use and is on my list. When you first start, you will need to confirm the use of a free license. Most likely, you won’t even have to go into the settings, because the program works great by default.

In the latest versions of Adobe Reader, there is still a very small opportunity to change the file. These are tools for highlighting text and inserting comments. The title “Text Highlighting” is probably not a very good Russian translation, because... “Text highlighting” is more suitable. To highlight the text, click on the icon in the toolbar and select the text, and the add comments icon is located immediately to the left.

By default, text is highlighted in yellow. You can change the highlight color only after highlighting with the default color. To do this, double-click on the selection and in the window click on the icon and select “Properties”. From there you can remove the highlight and add or change a comment.

Alternative programs for PDF

Acrobat Reader, of course, is far from the only PDF viewer. The developers managed to make an ordinary viewer a relatively heavy product. Basically there are no problems, but the program takes a long time to install and sometimes slows down.

Foxit Reader

The program is lightweight and has a simple interface. As a result, Foxit Reader launches quickly and is less demanding on computer resources.

Particular attention is paid to security, namely, at the first launch it is suggested to set the safe mode, in which attachments in the document are not opened and scripts are not run. Foxit Reader allows you to select text, insert comments, graphic objects, multimedia files (video and audio), but you can edit text only in the paid package Foxit PDF Editor.

However, over time, Foxit Reader has also become heavier, so I advise you to run its portable version.

Portable versions are distinguished by the fact that they are lighter and installation is very quick or not required at all. When you first start it, a window with two buttons will pop up, select “Not Now”. For the program to become in Russian, you need to go to the menu “File -> Preferences -> Language -> select Russian”

And restart the program with the “Restart Now” button.

The easiest - Sumatra PDF

This is already an open source project, the program is the lightest and is not at all demanding on resources. Can open not only PDF, but also CHM, XPS, DjVu, CBZ and CBR files.

Two versions are available: for installation and portable (works without installation). Since Sumatra PDF is already very lightweight, I advise you to download the full version, so you can immediately install the program to open all PDF files by default.

The program has practically no settings, everything is easy and simple.

How to open a pdf file? Which program is best to use?

PDF is a portable document display format created by Adobe.

The main feature of this type of file is that all elements of the document are displayed the same way, regardless of the device on which you open the file.

In PDF tables, there is no “misplaced” line formatting, problems with displaying fonts, or accidental deletion of data from an important cell.

There are sometimes problems with opening this format, for example, if the appropriate software is not installed on the computer, this will be discussed in the article.

Main functions of the format:

  • hyperlink support;
  • the ability to edit only in special programs;
  • free software to open pdf files.

Let's look at how you can quickly open the PDF format in modern computer and mobile operating systems, as well as using online services.

Best online services

If a program for opening pdf files is not installed on your computer, but you need to open the file immediately, you can use free online services.

An undeniable advantage of such sites is that they can be used on any device that has access to the global network.

KAKVSE

The first site, KAKVSE is one of the simplest and fastest online tools for viewing PDF, Doc or PostScript files.

You can view the file for free by uploading it to the site from your computer. The user can also enter an active link to the document in the appropriate line.

Let's open the document by uploading it to the service:

After clicking the View button, wait a few seconds for the file to be uploaded to the service. It will then open in a new website window.

To navigate through the document, use the toolbar, which is located on the left of the page. You can also use hotkey combinations to navigate:

  • Alt +N – next page;
  • Alt +P – previous page.

To return to the start page, press the Viewer Home button.

PDF Online Reader

The next good website to display PDF documents is Pdf Online Reader. The service has a well-designed toolbar and wide functionality.

To open the file, click on the main page Upload a PDF. Your device's file browser window will then open.

Select the desired file and wait for it to finish uploading to the site.

Navigation is carried out using the up and down arrows located at the top of the toolbar.

You can also go to the specified page, change the window scale and page width.

In addition to standard viewing functions, users can make some edits to documents:

  • adding annotations;
  • text selection. The text is highlighted automatically after the user has selected the fragment of interest;
  • adding external or internal hyperlinks.

The functionality of the service is demonstrated in more detail in the video.

Google Docs

To open a PDF document, go to the main page of the repository and click on the “Create” icon (on the left of the toolbar). In the drop-down menu, click "Upload Files".

You just need to drag and drop the desired document into the window that opens.

After a few seconds, the file will open in a new online viewer window.

Opening PDF in Windows

There are a huge number of utilities for viewing PDFs in the Windows operating system. Let's take a closer look at the best programs for different versions of this OS.

Windows 7

The key feature of the program is the presence of three modes for reading documents (page by page, two pages on the screen and “scroll”).

Users can quickly navigate through a file by searching for keywords.

Creating personal notes, highlighting text with multi-colored markers and scrolling with gestures make PocketBook one of the best mobile readers today.

ezPDF Reader

In this program I would like to highlight the quality of file display. All graphic elements (pictures, graphs, tables, notes) are highlighted in different colors.

Pages are turned using flips (a gesture that imitates flipping through a paper publication). Overall, users get the impression of reading a real magazine.

Open PDF on iOS (iPhone/iPad)

iBooks

On iOS devices, electronic documents, including PDF files, can be opened using the standard iBooks program.

Books also lets you open file attachments in email and Explorer.

Office Suite 6 iOS

If you prefer to use third-party software to view books and documents, we recommend choosing OfficeSuite 6.

This program is as close as possible in its functionality to a full-fledged document viewer and editor and is a kind of analogue of MS Office on a computer.

In the program you can view pdf or create documents in docx, xls, ppts format. Previously created docx office documents can be saved in pdf format.

PDF format in Windows Phone OS

One Reader

The program is distributed free of charge. It opens XPS, PDF, CBZ and password-protected PDF formats.

Users can instantly transfer open files via email, bluetooth, or upload them to SkyDrive cloud storage.

Foxit MobilePDF

Foxit MobilePDF is a cross-platform utility that has recently been available to Windows Phone users.

The application provides high-quality display of files in landscape page orientation, so Foxit is very convenient to use on tablets.

With Foxit Mobile, you can open, view, and annotate documents in files.

Portable PDF editors

PDF files are popular due to their cross-platform functionality and the quality of display of elements. As a rule, most free programs do not allow you to edit such files.

This is a privilege of paid software (Adobe Acrobat PRO, PDF Editor PRO and others).

However, there are still several free PDF editing programs available. As a rule, they are portable and do not require installation.

Because of this, the functionality is significantly reduced, but users can make basic edits without problems.

Foxit

One such portable application is Foxit PDF Editor Portable.

Developers offer a whole range of solutions for working with PDF, including mobile applications, auxiliary add-ons to the main program files, portable versions and much more.

The program allows you to edit basic elements (text, tables, delete pictures, change fonts).

Watch also the video tutorial about opening a pdf file:

If you have ever downloaded books, reports or other text documents from the Internet, then you have probably come across files that have the pdf extension. Finding themselves in such a situation, users often do not know how to open a PDF file. As a rule, programs for working with PDF are simply installed on the computer, which confuses many. In this article we will briefly look at a number of popular programs that allow you to open PDF files.

One of the most popular programs is certainly Adobe (Acrobat) Reader. This program is developed by Adobe. Adobe Reader provides the user with a full set of basic functions for reading and viewing PDF documents.

In addition to Adobe Reader, Adobe produces software for creating PDF documents. This is an Adobe Acrobat program. This program is paid and is available in two versions: Acrobat Standard and Acrobat Pro.

A few words about PFD format

PDF or Portable Document Format is one of the most common electronic document formats. This format was developed by Adobe Systems. The first version of the format appeared back in 1993. After this, the format actively developed. Almost every year it added support for new functions. Thus, during development, the following features were added to the Portable Document Format: password protection, Unicode support, interactive elements, links, digital signatures, transparency, text layers, forms, encryption and much more.

The main purpose of PDF is the publication of printed products in electronic form. Most professional printing equipment supports the format and can print such documents without additional processing or conversion.

At the beginning of its journey, the PDF format was not very popular. And there were objective reasons for this:

  • The necessary software to work with the format was paid;
  • The format did not support external links, which did not allow it to be fully used on the World Wide Web;
  • PDF files weighed significantly more than regular text documents. This also created barriers to using it online;
  • Processing documents in this format required significant system resources, which led to slow document display on weak computers:
  • In addition, there were other formats that created competition.

Now, none of these issues are relevant to the PDF format anymore. Adobe has released a free version of the program for viewing PDF files, and programs from other manufacturers have also appeared.
