A client recently had the need to convert a PDF document to a Microsoft Word document and enlisted our help. Short of purchasing the full version of Acrobat, or purchasing a single-purpose conversion program (which can run anywhere from $29 to $99), the alternatives were pretty slim. There are free conversion programs on the market, but the reviews were not overwhelmingly good.
Luckily, we discovered a free web-based conversion program that worked perfectly. It is called PDF to Word (free!) and while it claims to be a beta program, we had no problems. It preserved the formatting of everything, including placement of images and the formatting of a table. You simply browse to the location on your computer where the PDF file is located, enter your e-mail address, and about 3-5 minutes later, you receive the Word document in your e-mail.
Perfect for low-volume needs.
