I'm very careful of "free" utilities - more often than not they are loaded with, or are conduits for - spyware. These are totally safe, produced by the open-source community. These are what I use daily myself.
Paint.Net: Image Editor Similar in capability to PaintShop Pro v.8 or Photoshop 6 or so. A monumental open-source effort. Works great to tweak and resize images uploaded into Dynami Builder. http://www.getpaint.net/
PDF Creator Pro: Installs as a 'printer' and will turn any file into a tight .PDF with small file size. (many other competing solutions make giant files) http://sourceforge.net/projects/pdfcreator/ .
IzArc: WinZip Replacement. Even though XP/Vista will “unzip” a basic .zip archive, more often than not a “zipped” installer won’t run or install unless you have a real utility to unpack it. This one works just as well as WinZip and will save you $40. http://www.izarc.org/
FileZilla: FTP Software. Equiv to CuteFTP or WS_FTP. A server version is also available. http://filezilla-project.org/
