Y2mate.com is a bit less flexible than other online YouTube converters because it can only download and convert YouTube to MP3 or MP4. If you want to download videos from other websites like Facebook and Dailymotion, you need to try other tools.
Y2mate is a good tool to download and convert YouTube videos into music. This online YouTube converter does not work well with Android but can work well on other devices. And, you can download YouTube videos in all browsers.
