I found an awesome online file conversion website called Zamzar. You can upload files or send youtube links to their site and have them converted to other formats. Enter your email and they’ll send you a link to download your converted file.

This is a great service for teachers who receive papers from students that save their documents in programs like Microsoft Works (.wps) or Office 2007 (.docx) format. Also great for those who like to show youtube videos in the classroom but would rather download the videos for future use instead of reloading a page and waiting for their video to load.
