As you might know, PDF, which stands for Portable document format, is a format that contains text and can be read using Adobe Reader or similar applications. Every PDF file is generated according to a specification. PDF has got different versions and sometimes you need to download a newer version or convert the PDF file to a newer version, so that the program you use can read it. That's why you need PDF Version Converter 2.0. This software enables you to convert PDF files from one version into another in a very simple way. You will no longer have to worry about the version of your PDF files.
This software enables you to convert your PDF files to PDF versions 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 and 7.0. The application's main window is extremely easy to use. All you have to do to convert one version into another is to add the file in the program's main window by simply clicking on the add PDF file button, then choose the output version and folder and then click on the convert button. You will notice that the software converts the files almost automatically. Once the conversion is done, a message will pop up on your screen; you can open the file by going to the previously selected output format and double clicking on it.
I'm sure that the reason why there is no help menu on the program's main window is that no one would need it.
