Sometimes we find ourselves using computers where we can not install programs, like a public computer, such as school or library, or computer in the workplace.
But, sometimes happens that I want to convert an audio or video file at work, but I can not install a converter... how can I do?
Mediaconverter.org is an online service that allows you to upload audio/video files and convert them.
It's free (freemium), and is very convenient. Of course, for the most demanding users who wants to convert large high-definition is not really suitable, but is perfect for small uses.
