Something to download playlists of youtube vids?

Looking for something that can download a whole playlist of youtube videos at a time. I found something called 4k Video downloader that claimed to be a free way to do what I wanted but when I actually tried to do it it said nah you can’t do that on the free version (even though that’s exactly what it advertised -_-).
Can anyone help direct me to something like that?
Cheers
