There are times when I need to convert a file from one format to another. A free online tool that supports conversion between different file types is Zamzar. Zamzar’s simple interface makes converting files easy and I don’t have to create an account to use it. I’ve found Zamzar useful when adding files to websites. For example, I can use Zamzar to convert a Windows media file (.wmv) file to a Flash video file (.flv) that will play in Moodle or Mahara.
Zamzar can convert document, image, music, video, ebook, compressed, and CAD files from one format to another. To see more information about the types of files Zamzar converts, click the following link: http://www.zamzar.com/conversionTypes.php.
