I have created a free online media conversion application.

It allows you to record, convert and download nearly any audio or video URL to common formats.
It supports all the major services: Direct Download, YouTube, Dailymotion, Vimeo, Metacafe, Myvideo and more.
You can download your converted file to desktop computer or mobile device using especially generated QR code,
or save them to Google Drive or DropBox.

I would like to hear what you think about my application, and if you find it useful.
Any comment will help me improve it.
