Websites may not be the best YouTube to MP3 converters, but they're more lightweight - no need to install, and the interface is simpler. An online downloader is useful if you're in a hurry and don't need to download long videos or playlists. They are also easier to access, since the downloads occur completely in your browser. However, some desktop apps include the functionality of online downloaders.

Airy - a Desktop Alternative

All the aforementioned online services have serious downsides. Video length limits, low speeds, ads, limited format options. An offline app is better than the best online YouTube to MP3 converter. Desktop apps have none of these restrictions - they download videos directly to your PC and convert them using your own desktop CPU, which is usually faster.

These advantages put Airy - a Mac and Windows YouTube downloader - far above any online service, just from a sheer technical standpoint. It downloads playlists, video, audio, private and age-restricted footage, even entire channels.

icon cons Cons

This site has been around for a while, and even went through a lawsuit once. It records media very slowly - a 10 MB audio file might take forever to download, let alone a 100 MB video. The interface is also not as simplistic as you’d find on other sites. Still, it can convert and download, both audio and video, and even cut them.

In Summary

Despite there being a large amount of different solutions, we recommend that you consider our list first and foremost, as we’ve chosen some of the best apps internet has to offer. Personally, we recommend desktop apps like Airy, as they provide the safest and the most feature-rich experience you’ll find. Not to mention, no ads.


Looking to download songs and playlists? Wondering how to convert YouTube videos to MP3? You need a downloader app. Airy has an option that allows you to download YouTube audio separately from the video and convert it to MP3.

  1. Install and launch Airy.
  2. In your browser, go to a YouTube video.
  3. Copy the URL.
  4. Paste the address in Airy.
  5. Set the format option to MP3.
  6. Click "Download".

Any of the ones we’ve mentioned on this page are good, but none of them are perfect. If you want top performance, you should look for a desktop app - for example, Airy. Like any fully-fledged app, it offers playlist downloads and conversions, and works quickly.

Downloader websites always pose a certain risk, since the ads found on these services may be unsafe. This is not the case with Airy - a completely ad-free downloader that doesn’t gather your data.

YTMP3 doesn’t offer download options for higher-quality YouTube audio formats, such as 48 kHz WebM Opus. It downloads lower-frequency M4A. On the other hand, the difference is negligible.
