CutePDF is a Windows-only free option for creating PDFs. Much like Adobe Acrobat, CutePDF allows you to print your documents as a PDF. While the product is free, at the push of a button it is possible to print reliable PDFs from any file format. This piece of software is the free version of the more advanced CutePDF Professional which allows advanced form and editing capabilities. For basic PDF creation needs, this is an excellent product.
