What is PUB file?

The files of the type .pub refer to Publisher files. These are the graphics or web pages developed using the Microsoft Publisher software.

The .pub file is a versatile format that allows to store both vector and raster graphics along with many other features such as HTML content to create beautiful designs and webpages. The publisher files can also be used for creating Marketing material, brochures and newsletters.The publisher files were widely used a few years back when it was difficult for laymen to make webpages. Now that advanced web editors are available, the publisher files are used mostly for the designs and marketing materials.

Program(s) that can open the .PUB file


If you cannot open the PUB file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable application that supports PUB among those that are installed on your computer.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the PUB file can be found below. Now just download and install the appropriate application.

This site also defines other possible causes causing the problems with PUB files.

Possible problems with the files that are in the PUB format

The inability to open and operate the PUB file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Microsoft Publisher Document Format file. Below is a list of possible problems.

  • Corruption of a PUB file which is being opened
  • Incorrect links to the PUB file in registry entries.
  • Accidental deletion of the description of the PUB from the Windows registry
  • Incomplete installation of an application that supports the PUB format
  • The PUB file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the PUB file.
  • Drivers of equipment used by the computer to open a PUB file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the PUB file should operate with your programs without any problem. If the problem with the PUB file has not been solved, it may be due to the fact that in this case there is also another rare problem with the PUB file. In this case, the only you can do is to ask for assistance of a professional staff.

Is there a universal way to open unknown files?

Many files contain data in the form of text or numbers. It is possible that while opening unknown files (e.g. PUB) a popular Windows simple text editor, which is Notebook will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
