Kvisoft PDF Merger is a program that unites two or more PDF or/and image files into a single PDF. In addition, you have the possibility to secure the output document. This application can be easily installed and occupies very little disk space.
The interface is simple and intuitive, providing self-explanatory buttons placed at hand.
I personally like to have the support of a large working area when using a program, but this app doesn’t allow you to maximize the main window. After you add the files to the program, it gives you the opportunity to order them differently. Moreover, you may enable security setups. Thus, you have the possibility to set a password for opening the output file, as well as for sending the newly created document to a printer. You can also put restrictions for editing or copying the new file. These constraints can be overcome by typing the right password. The application offers the means to change the title, the subject, the author, and the key-words of the output file. A good thing is that the merged document preserves the quality of the source files. What's more, the program deals with image files having popular extensions (.JPG, .JPEG, .GIF, .PNG, .BMT, etc.). What I also appreciate about this tool is that you have the possibility to select only some pages from the input files and merge them with other source files.
I recommend this program because is easy to use and has a simple interface, without complicated commands. As far as I'm concerned, the most important feature of all is that Kvisoft PDF Merger is able to unite both PDFs and pictures in one single file.
