No need to say that Doc format is very popular among users due to the popularity of Microsoft Office tools. At the same time, however, experienced computer users are aware of the fact that Doc files are not as secure as PDF documents are. So may people have to convert Doc files to PDF.
When it comes to converting one Doc file to PDF, no one seems to have any problems. Microsoft Word allows saving its files as PDF. But if you want to merge many Doc files to PDF you'd better use 3rd party software to save your time. CoolUtils presents PDF Combine Pro, a unique tool designed to merge several Doc files into one multi-page PDF. Here are only a few things that make PDF Combine Pro so outstanding:
