Overview of YouTube HD Downloader by MP3 Toolkit Benefits
Another excellent feature of This application is it was designed for HD video downloading. YouTube has started to store all videos as HD (High Definition, 720p, 1080p or higher) format on the server side since a few years ago, and every HD video file has been separated to a video part and an audio part. Additionally, Most of other YouTube video downloading tools only downloads normal resolution videos (like 640 or 480), but YouTube HD Downloader could download both 2 parts of a video and merge them to the HD video. That means you could download and save videos to your PC as the best quality.
