Convert M3U8 to MP3

Converting UTF-8 M3U Playlists directly to MP3 Audio Files (.m3u8 to .mp3 conversion) is not possible, since M3U8 playlists do not contain any media data.

If you want to convert media files, referenced by your M3U8 playlist, to other formats, you must first locate/download those files. You can then easily convert those files using most available media editing programs or (online) conversion tools.

Simply put, it is impossible to convert M3U8 to MP3 directly.
Thus, there is no so-called m3u8 to mp3 converter or a free online m3u8 to mp3 converter to be found.
