Zamzar is a web application to convert files. It was created by brothers Mike and Chris Whyley in England. It allows user to convert files without downloading a software tool, and supports over 1,000 different conversion types. Users can type in a URL or upload one or more files (if they are all of the same format) from their computer, Zamzar then converts the file(s) to another user-specified format. For example, from an Adobe PDF file to a Microsoft Word document – users receive an email with a URL from where they can download the converted file. It is also possible to send files for conversion by emailing them to Zamzar.
