The List of 7 Best YouTube to MP3 Converters Online/Desktop 2020

Y2mate.com is one of the best free YouTube to MP3 converters in the eyes of many experienced users. The whole site is designed with a fresh layout and is multi-language supported. No ads, no pop-up, no malware, and no registration, Y2mate.com provides a safe and clean environment for your conversion.

YouTube to MP3 conversion is easy and fast and is offered in multiple qualities, ranging from 64 ~ 320 kbps. If you switch to the YouTube Converter/Downloader, you'll also get audio in M4A 128kpbs (M4A is a file extension for an audio file encoded with AAC. See the differences between AAC and MP3). Downloads are unlimited. There is no limit on the length and size of the video as well.

Besides audio conversion, Y2mate.com can also convert YouTube to MP4, 3GP in various resolutions. Y2mate.com claims to involve downloads from other sites like Instagram and Facebook too. But we found it not working as expected. 

One last thing about Y2mate, it is full platforms supported and has a browser extension and an Android app available.

EasyMp3Converter is the purest YouTube to MP3 converter. It has no other converting features like the other converters but only the YouTube to MP3 conversion function. And that’s what makes it unique and precious.

Its interface is also outlined most comfortably with no ads and pop-ups.

With no other distractions, EasyMp3Converter focuses entirely on YouTube to MP3 conversion and offers the fastest conversion speed. The quality is offered in multiple options, from 64 to MP3 320kbps. There are no restrictions on the length or the size of the video converted, and you can make conversions as many times as you want. No registration is needed as well.

EasyMp3Converter is compatible with all browsers from Chrome to Opera.

Mp3 YouTube is another best site to convert YouTube to MP3 free. It has a sleek-designed interface that is multi-language supported. No ads and pop-ups are presented on this site either, hence securing you a smooth conversion experience.

Converting YouTube to MP3 is simple and in high-speed on Mp3 YouTube. The final converted audio source for downloading is automatically offered in the best quality (the original quality as it claims). So there will be no options for you to choose manually, and such service is convenient for people who require straight downloading.

There are limits on Mp3 YouTube as well. It cannot help you to convert video longer than 90 minutes and size larger than 200MB. The number of conversions per minute is also restricted.

Mp3 YouTube also supports downloads from other sites like Facebook, Vimeo, Soundcloud, Instagram, etc.

4. YTMP3

YTMP3 is regarded by some users as one of the best free YouTube to MP3 converters online. The self-explanatory interface of YTMP3 puts no pressure on its users to start a fast conversion of their desired YouTube videos instantly.

The converting process usually takes one or two seconds. And then, you are offered choices as to download, save to Dropbox, or continue to convert the next video. You can also choose to download your video as either MP3 or MP4.

Like Mp3 YouTube, it claims to auto-convert YouTube to MP3 in the highest available quality. But we found in our test that it can only convert audio to half of the original audio quality. (We tested it with an MP3 320kbps song, and the converted result is in 192kbps). So if you are high-demanding about the audio quality, this site may not be the best site for you. However, if you care more about the speed and convenience you could get, then this site remains a nice go-to place for you.

There are several caveats, though. YTMP3 does not support video longer than 1 hour. It is not compatible with the iPad or iPhone as well. And, beware of the false convert button (ad) placed beneath the real download button.


FLVTO adopts a more fancy appearance that makes other similar sites look monotonous. However, it is ads-covered that it might be a little annoying to people who want a neat environment.

It does a good job of fast converting YouTube to MP3, MP4, AVI, MP4 HD, and AVI HD. Yet it can not get you the original audio quality but reduce the quality by half. Also, FLVTO cannot convert YouTube to MP3 longer than 2 hours.

Apart from YouTube, FLVTO also supports video URL from Instagram, TikTok, etc. It is all platform compatible as well.

320YouTube is the best YouTube MP3 downloader to save your MP3 in the best MP3 quality since it only converts YouTube videos to MP3 320kbps. The conversion process is also smooth and fast and without ads-interfering. If you want all your MP3 music collected in fine quality, do not throw away your shot at this site.

Nevertheless, you should make sure the bitrate of the original audio source file is not lower than 320kpbs. Say if you convert an MP3 128kbps audio to 320kpbs, you won’t get a real 320kpbs quality audio. Instead, you might get a worsen quality audio with a larger file size.

320YouTube has an extension that works with all browsers like Chrome, Firefox, Safari.

BY FAR, we’ve listed the top 6 best YouTube to MP3 converters online. As you can see, online converters have more or less several limitations, such as restrictions over the video length and size, lack of audio quality options, and most evidently, unable to download a playlist at one go. You would find online conversion an optimal solution when you only need to make one or two conversions once in a while. But if you are to download regularly, you’d better stick to a desktop video converter instead. And for that matter, we also have a recommendation for you.
