This is by far one of the best ways to convert entire YouTube playlists in MP3 formats for free.
You also have the option of buying a one-time $15 premium key through which you can convert entire YouTube playlists to MP3 files. You just have to turn on the Smart Mode and you can extract MP3 files from YouTube video with just one click. The best part about the 4K video downloader is that it offers an uncluttered and simple user interface with barely any ads. If YTMP3 is best for online YouTube video to MP3 conversion, 4K Video Downloader is the best MP3 converter for ripping audio offline.
