Youtube downloader is an amazing application to download videos in it’s true HD quality and format. Other video downloader generally compress and compromise with the quality of HD videos but not YD. It has a built in codec for true HD link conversion and downloads directly from the channel source of the video. The size of the videos are decent too.
When your IDM fails to download those mkv files, youtube downloader hd always come to your rescue. a must have app and recommended to my fancy web surfing viewers.
