PDFCreator Freeware by pdfforge

view all images (3) This program is one of the oldest PDF creators that will convert printable files to PDF format.

It works like a virtual printer, after you send a file to Print, choose PDFCreator as printer and your file will be saved as PDF. Instead printing on paper, this "virtual" printer will save the file on your hard drive.

There are available many advanced options, but these are pretty hard to understand and to use, unless you take some time and have patience to play with it.
