Ghostscript isn't often found on Windows systems, but it's a huge toolbag of useful stuff for doing things with Postscript and many kinds of PDF files. If you install the GIMP (free almost-equivalent of Photoshop) Ghostscript is the tool that it uses to import PDF files into graphics images. On Linux I use GS for converting PS output from abcm2ps into either PDF to email tunes to people who don't want ABC, or into graphics images for importing into documents. It's the basis of viewing and printing programs too.

Oh yes, and it's quite safe!
