While it can create the PDF's and other formats it is not always the right tool for all users. It is not useful for users who want to create fillable form PDF's. If you want to create a straight PDF or the other file formats PDF creator is the right tool for the job.
I always remove the toolbar that it offers to install as part of the program.
PDF creator can be download here: http://sourceforge.net/projects/pdfcreator/
