Though its name might lead you to believe that this program only converts into MP3 the audio of 4k videos from YouTube, 4k YouTube to MP3 is a bit more versatile than that. Actually, it does convert any online video (regardless of its resolution) or audio file from VEVO, SoundCloud, Facebook, Vimeo, and many others into M4A and Ogg as well, including entire YouTube playlists and channels.

Before actually converting any audio stream into MP3, Ogg, or M4A, what 4k YouTube to MP3 does it to extract one of the audio streams associated to the online video selected and convert it into the output codec of your choice. You can mix videos and audio files from different sources on the conversion list in the program’s main interface, and all of them will be converted into a format and a bit rate of your choice. By making use of multi-threading, it can batch-extract and batch-convert a long list of tracks simultaneously, though do not expect lightning-fast conversions.

When more than one are available, you are not allowed to choose which of the audio streams will be used as source – the program will make that decision for you automatically. As for the output, if you select “Original” in the Quality drop-down menu, the program will simply grab the stream and will save it as is in the folder you selected, but if you want the program to convert it, you can choose among three fixed bit rates (128, 256, and 320 kbps) and their corresponding levels of quality (low, medium, and high, respectively). I’m sure some users may want to have a more flexible choice at both ends, but given the overall low quality of the audio streams used for online videos, I find the options it offers to be quite reasonable. The program comes with a built-in audio player for you to check the resulting audio files straight away.

Though you can use it as a free tool, if you want to enjoy 4k YouTube to MP3 without any limitation in the number of playlists, channels, audiobooks, or other files that you can download, and without any ads, you are advised to go Premium for a small fee. It is simple, effective, and convenient – a good solution to turn into portable audio files bulky high-definition online videos.
