And then there's online do-it-all file conversion service Zamzar. Zamzar lets you convert media files, documents, images, pretty much anything. Zamzar is a web based service, so it might take a little longer to convert some files since you need to upload them to a server, wait for the conversion to complete, and then check your email inbox for a download link. But as a web based application, Zamzar is useful for Windows, Mac, and Linux users whether they're at home, work, or using a library computer.
When we first reviewed Zamzar over a year ago, one of the free service's limitations was that you could only upload files up to 100MB at a time. Now Zamzar is offering premium accounts that allow users to convert files up to 1GB (which could come in handy if you want to convert video files).
