Media-Convert is a fairly impressive web service that will convert a file from one file format to another. That sounds pretty benign, but what's impressive is how many formats it supports. There's a good chance Media-Convert supports almost every document on you computer, including dozens of audio and video formats, a ton of common and obscure image formats, documents from Microsoft Office, OpenOffice.org, and others, compressed archives, and more. One particularly neat trick it can do is convert PDF documents to Adobe Flash (SWF) movies. It can also capture web pages as images, convert Microsoft Access databases to Excel spreadsheets, and, in case you're into this sort of thing, convert text documents to morse code. Of course, it's not lightning-fast. You have to upload your file or enter the URL of a file and then wait awhile while it's converted, but far as convenience and price (free!) goes it can scarcely be beat.
