Your free online file converter. With the different types of file formats available on the Internet, it is always good to have a site which helps you convert one to another. Zamzar has it all, you can convert video files, audio files, image files, documents, CAD formats and even eBook formats. Heck, you can even let Zamzar download videos for you from youtube or other video sharing site and have it convert into a viewable format for you. You can also sign up for Zamzar services - you get a larger size for your files. I love this site and have been using it since 2007.
