Have you ever wished that you could convert your flyers, reports, newsletters, resumes, or whatever into PDF format? PDF is the best format for distributing documents, hands down. PDF files are accessible to everyone and print reliably. Most users are not able to modify them either. The problem is, converting your files into PDF format requires that you buy Adobe Acrobat Standard for about $299, right? Nope. Enter CutePDF Writer. A FREE program that easily converts your documents to PDF. No popups, no expiration times, no hassles. Cute.

Note:  CutePDF Requires a PS2PDF converter such as Ghostscript (recommended).  You can get the free GPL Ghostscript 8.15  here.
