Covert Online ..

Ever tried to convert a file format to another but have to install a software.
So now comes a web application which woulddo this for you and that too online... yes online.
Media Convert lets you convert a huge number of formats: from images, audio files (you can also split the files), videos, archives and documents. Media-Convert is 100% free. No software is needed, and you don't have to register. You only need your favorite Internet browser. Your files are ready 7/7 days 24/24 hours.

Zamzar offers less formats, but it lets you convert up to 5 files at once. When converting more than one file, you can download all the files in a zip archive, like in Gmail.

So now you have one more power added to your list of web applications.
