FormatFactory

A handy all-in-one utility for taking one kind of audio, video, or picture file and converting it to another. The interface is a dead-simple drag-and-drop affair, and it's meant for running batches of files through converters—FLVs to Windows Media, MPEGs to iPod-friendly video, DVDs to DivX files, etc. You won't get a lot of options for quality control, compression rate, or other tweaks, but for some folks, that's really a benefit. FormatFactory is a free download for Windows systems only.
