In this post, you will find our list of the best free YouTube to MP3 converters. Whether you want to listen to music from a video offline whenever you like or turn your favorite YouTube channel into a podcast that you can enjoy while working, here you will find the best YouTube to MP3 converters for this task.

Some of these tools are simple-to-use free choices, but you will also find premium choices with more advanced features like 4k and 8k resolution support (most of these tools are both YouTube to MP3 converters and YouTube downloaders).

If you're looking for a fast, flexible YouTube to MP3 converter, this is the tool for you Any Video Converter will probably cover your needs.

YouTube to MP3 conversion is not the program's sole purpose; it has many more features than what you might need including converting DVDs and ISO images, recording and capturing from other devices, and creating customized DVD menus.Regardless, make sure that you don't install any adware when you perform the installation.

Downloading MP3s with Any Video Downloader is as simple as pasting in the URL of a YouTube video and waiting for the download to complete. You can then select MP3 as the output format and hit the Convert Now button. There is no one-click option, so you will have to be content with two or three.

What to Look for in YouTube to Mp3 Converters

When you're looking for a YouTube to MP3 converter, one of the first things to consider is how many videos you want to convert. If you're only going to be doing it once or twice, it might be worth considering an online tool, but for anything more, it's worth downloading a dedicated desktop application.

The desktop software will also be faster because the data isn't processed on a remote server. Finally, some converters are also able to process multiple YouTube videos to MP3 format at once.

Online Video Converters to MP3

I cannot ignore this option due to its simplicity. Just type YouTube to Mp3 and search for it on Google. The first site you find will definitely be an online YouTube to Mp3 converter (unless you get this post to the first page on Google). The first thing you will see is a page with a field to paste a YouTube video URL and process convert. However, if you are looking for the best YouTube to MP3 converters, or for a solution that supports other formats and lossless transcoding you should go for a premium tool.
