Best YouTube to MP3 Converters of 2021

Who doesn’t love YouTube? It’s not just a source of entertainment, but it’s also a fantastic way to keep up with old and new tunes alike.

However, when it comes to listening to music, YouTube has some limitations. For example, you can’t close the app and listen to songs, nor can you easily download just the audio of a video to listen to later.

While a Youtube Premium subscription solves some of these issues, you might only be after a few audio tracks that you enjoy.

This is where YouTube to MP3 Converters come in. As the name suggests, this software takes a YouTube video and extracts the audio track so that you can download it to your device to listen to at any time.

However, YouTube has copyright policies limiting what people can download, play, sell or lend. So before you proceed with this article and the use of MP3 Converters, browse YouTube’s Terms of Service to avoid the unlawful exploitation of video or audio on the platform.

If having done that, you’re still after a YouTube MP3 converter with these disclaimers in mind, read on! We’ve reviewed some of the best Youtube MP3 converters of 2021.

What’s a YouTube to MP3 Converter?

As we just hinted at, YouTube to MP3 converters transforms YouTube videos into MP3 files. Often, these tools are available as browser extensions where you just paste a YouTube URL into a search bar. Then, when the conversion process is complete, you can download the MP3 file for the video you’ve entered.

Once you’ve downloaded an MP3 file, you no longer need to rely on an internet connection to listen to your favorite songs. Instead, you can play the files on any device that supports MP3.

Many YouTube to MP3 converters offers a more comprehensive range of formats than the name suggests. Depending on the tool in question, you may also be able to convert videos into MPEG4, OGG, WMV, Theora, OGG Vorbis, and other formats.

While many converters are available on the web, finding those that actually work can be challenging. Many are riddled with malware and bugs and provide a poor user experience. That’s why we’ve identified only the best converters for you.
