How To Convert YouTube Videos to MP3 Files [2023]

There are countless music apps on the internet, but let’s face it — sometimes we can’t find a song or remix… not even by asking on Reddit or using an app like SoundCloud!

That’s when software that helps convert YouTube videos to MP3 files comes in handy.

Many of these apps are online and come with a free version, but you may want to consider upgrading to something more robust with additional features that will save you time.

Other reasons you may want to convert a video to an MP3 file include saving space, making music portable, maintaining sound quality, creating playlists, and recreating the audio in videos into creative edits.

YouTube’s copyright policies do not mention anything explicitly about video-to-MP3 conversion. However, there are some ground rules to downloading converted videos from the service.

It is not illegal to convert YouTube videos to MP3 so long you are downloading the music for personal use only. Re-uploading it to the internet is a big NO because then it would be copyright infringement and you may get in trouble. Even if you are downloading a YouTube video’s MP3 file to add to your own app or website, you will need prior permission from the video’s copyright owners as you’re using a core part of their content. 

You can look at it the same way people in the ’80s and ’90s would use cassettes to record music off the radio. But even so, it is best to not go overboard and download 100s of videos as MP3 as a replacement for a music app.

In case you want to convert YouTube videos to MP3 for any kind of creative or professional use that includes re-uploading or redistribution, make sure you use music with a Creative Commons License. Watch out for videos with Standard YouTube License and/or a Content ID claim on them, using them will lead to copyright infringement.
