You can download any YouTube video just by typing “ss” before the “youtube” part of a video’s URL link in your address bar. Here’s an example for Adele’s Hello music video:
Original – www.youtube.com/watch?v=YQHsXMglC9A
Download – www.ssyoutube.com/watch?v=YQHsXMglC9A
Not only can you choose from different file types but also any resolution up to the original quality. Just remember downloading copyrighted content from the internet is illegal.
