Adobe Acrobat documents, also known as PDF (Portable Document Format) files have become commonplace on the Internet and in business. With CutePDF, you can turn almost any document straight into a PDF file, except that unlike Adobe Acrobat, CutePDF offers a totally free version.

Like the official Adobe Acrobat Distiller application, CutePDF acts like a printer, so any document that opens in a program that allows printing (just about everything) you can select CutePDF as a printer and send it off, you will be prompted for a location for your PDF file and that’s it, your file is ready.

Note: You’ll also need to install a free PS2PDF converter, which is also available from the CutePDF site, here.
