Convert YouTube to MP3 Online

Unlike desktop apps or browser extensions, websites will require no installation or setup to download MP3 from YouTube pages. They are always available to use, as long as you have a good connection and a compatible browser.

This is the slowest method by far, because the files are downloaded twice – once to the conversion servers, and then again from the servers to your PC. But it’s an easy solution when you’re wondering how to convert a YouTube video to MP3 on Mac or Windows PC.


A novel feature that you’ll find on Y2Mate is the presence of quality options for MP3 files. You won’t get better quality from YouTube audio, so these are compression options. It’s usually not worth it to compress sound files any further than the levels you find on the platform. But if you’re running out of space on your SD card, it’s better than nothing.

Download MP3 files in a couple of clicks with Y2Mate


  • Minimal ads
  • P3 files can be compressed further


  • High compression is pointless and it doesn’t sound well

Browser Extensions on Mac & Windows That Work Currently

Browser extensions are wildcards. They are light, simple and chaotic. Anyone can make and publish one, with no legal or financial accountability that comes with company-developed tech. And this pile of nasty spyware and low-effort clones has some real gems in it.

But lately, YouTube’s been hard at work, enforcing its overbearing TOS. Many browsers and marketplaces have created obstacles for any converter that might pop up. Worry not! Our suggestions are tested to work even now, in 2023.

Firefox Add-on Downloader

Firefox has a lot of choice when it comes to downloader plugins. We recommend DownloadHelper. There’s only one downside – it’s a two-part installation with a desktop component. You’ll have to get the secondary installer from the official site.

But, once that’s done, you have an excellent app. One of the better YouTube to MP3 converter Mac and Windows PC add-ons. Other than downloading, this plugin allows you to see a lot of information about the videos. It keeps a file history for further convenience.

  • Detailed interface with many functions


  • Needs a two-stage installation
  • You might as well install a desktop app

YouTube Video Downloader by Addoncrop

Chrome Web Store Developer Policy is the shackle that keeps mankind from ascension. At least, it keeps us from downloading YouTube videos in our browsers, which, arguably, is not that far off. Fortunately, there are workarounds.

The Web Store still hosts Crosspilot, which, in turn, allows you to install Addoncrop plugins. And those are very similar to Y2Mate: push button, get video. There’s a bit of variety about Addoncrop that Y2Mate might not provide. But then again, it’s a third-party app on a third-party platform; will you be brave like us? Will you dare?

Addoncrop is very similar to Y2Mate and has option variety


  • Option variety
  • It works on Chrome
  • You will feel like a hacker


  • Shady
  • Complex installation

YouTube Premium – Ups And Downs

YouTube Premium allows you to watch videos, sans any ads. It also includes the option to download videos and audio for offline consumption, among many other functions. But does it make sense to pay for it?

A month of YouTube Premium will cost you $11.99 a month. Quite the price tag! Still, there are a lot of perks you get for the trouble. Similar to downloading the files with a YouTube converter to MP3, you will get the ad-free experience, while storing and watching clips to your heart’s content. That makes it worth considering if your Internet connection is not stable.

And what’s the other side of the Premium coin? It’s the alternatives. Can it compete with a YouTube to MP3 converter Mac and Windows PC?

Paying for a service that’s already freely available seems unreasonable. If you’re stingy, it’s hard to justify going from 0 to 12$/month for a service you might not even use all that much. And over long periods, these twelve bucks could add up to a freaking fortune, inflation notwithstanding.

What you should consider is how much you actually use YouTube. Who knows, maybe spending your day watching seminars is a day job – if that’s the case, it even starts sounding like a bargain. But if it’s just a couple videos to kill time in the subway… Well… Maybe the best YouTube to MP3 app can beat it.

Just keep in mind that over a year, your expenditures will fall slightly short of 144$. And that’s what you’ll spend for something that you can get cheaper, or even for free. Remember that there is always a YouTube to MP3 converter Mac free out there… Think carefully before you sign up for this.

Try YouTube Premium and get the ad-free watching, while storing and watching clips to your heart’s content


  • Listen to anything instantly, without the need to download
  • Access to YouTube Premium-exclusive music


  • Requires constant internet connection
  • Subscription-based, you don’t get to keep the music
  • Expensive in the long run

How to Choose the Best YouTube to MP3 Converter App

With the available variety of YouTube converters, it may be hard to decide which one to choose, especially if you’re considering paid options. But we have some advice that can help. Here’s what you should consider when choosing a YouTube to MP3 converter for Mac.

  • Conversion formats. Your app of choice should be able to download YouTube videos directly into audio files.
  • Playlist downloading features. And make sure that audio conversion can be enabled for the entire playlist at once.
  • Ease of use. It shouldn’t be difficult to use the app.


And finally, when you’re looking for paid converters, consider only the ones that have demo versions. YouTube updates often, and this breaks many related apps. Trying out a demo is absolutely necessary for YouTube downloaders, since otherwise you risk wasting money on a broken app.

That’s it, good luck!

On Audio Formats and Their Utility

Lossless or lossy? Open or licensed? Even if you’ve already got a YouTube MP3 converter for Mac or Windows OS, you still have to choose the format. It’s a matter of compatibility, quality, portability and basically everything else. There is no objectively “wrong” format, but depending on your needs, selecting some formats could lead to useless files that don’t fulfill your needs. To save yourself time later, read up now.


MP3 is both a container file and a compression format. When compared to raw audio data, it can reduce file size by a factor of 12. Of course, there are drawbacks. During compression, some quality is irreversibly lost. An MP3 can never be restored to its initial quality, so it may be a poor choice for archivists.

On the other hand, if you don’t care about hi-fi sound, it will allow you to pack dozens, if not hundreds of albums on a single SD card. And how would we rate the best YouTube converter if it didn’t exist?


The AAC-encoded M4A file is the designated successor to MP3. While the world stubbornly refuses to move on, and a ton of data is still kept in MP3, this “newcomer” offers an objective improvement on the quality to size ratio.

The stigma on M4A is absent from Apple platforms and devices, as the company proves time after time its dedication to MPEG formats. But even on other systems, compatibility is hardly an issue nowadays. Media players try to reach as many formats as they can.

OGG (Vorbis, FLAC)

OGG is a container format. Though unassuming, it is a part of a well-developed open-source multimedia framework. And the framework includes a vast number of various codecs, both lossy and lossless, that are intended for specific tasks. Depending on its codecs, an .ogg file can be best suited to streaming, podcast audio, normal everyday music or even ultra-HQ audio preservation. And all of that comes with metadata support. We will give 2 examples of OGG-supported codecs: Vorbis and FLAC.

The most popular OGG codec is Vorbis. It has a broad range of workable bitrate, decent compression and compatibility. This is the codec you want for everyday use: songs, audiobooks, recordings, etc. There’s not much to say about it outside of technical stuff; in practical terms, the quality is comparable to MP3 and AAC.

And how could we forget FLAC? While it doesn’t provide shrinkage at the same level as MP4, only about 50 to 70%, the audio file can be restored completely, without a single bit of data loss (unless there is a malfunction). Though there are often arguments on whether the human ear can even sense the difference between high-quality lossy and lossless audio, it’s still nice to have the option.


Windows Audio Interleave is a slightly-dated, proprietary format. While it has some serious limitations, and generally larger filesize, there are some notable features, such as XMP metadata support. It’s a poor choice for general use – only go with this one if you have specific demands and in-depth knowledge of media technology.

This list of solutions should give you a good idea on which converter to choose. YouTube to MP3 converters, including Airy, all have their individual upsides and downsides. It’s worth remembering that the overall best downloader is not necessarily the one you need in your situation. We hope that you’ll manage to choose the right tool for the job.

Frequently Asked Questions

We’ve put as much info as possible in the article so far, however, we are sure there are still some unanswered questions about formats and Mac YouTube converter solutions. That’s why we put together some frequently asked questions and answered them.

YouTube is filled with videos from users from all over the world. And while some of the downloaders available come with restrictions when it comes to downloading copyrighted audio, Airy is a software that will get the job done excellently.

Here’s how to use it:

  1. Visit YouTube and choose the video you want to convert to audio and store on your Mac.
  2. Grab the URL for the video and paste it in Airy.
  3. Select the audio media format you want from the list.
  4. Press download and get the file saved on your Mac.

Many YouTube downloader MP3 apps are also compatible with smartphones as well. Just add the app on your phone and follow the same steps as above. If you can’t find an app that would work directly on your phone, you can simply synchronize files through iTunes and get all the downloaded YouTube videos on your iPhone.

We’ve described some online solutions in this article. According to your requirements, you can choose the one that perfectly suits youк usage scenario. Each of them has its own advantages and disadvantages, that is why to have one perfect choice for lots of users is almost impossible. Read the article, check the comparison table, and choose your best YouTube to MP3 converter.

Airy is the way to go. Try this:

  1. Download Airy and set it up.
  2. Open your browser, navigate to a YouTube video page. Copy the address from the text bar at the top.
  3. Open Airy and paste the address into the search box. Select “MP3” from the format drop-down menu.
  4. Click “Download”.

In some ways, it can be, but in other ways, it may not be. It’s not as black and white as one would think.

Normally in all circumstances, downloading content from a public or private platform can infringe upon copyright laws. For YouTube, this would go against their terms of service. But at the same time, there is no real law and enforcement of stopping users to download content for their personal use.

There is no clear, explicit law that would stop someone from doing so. Technically if one were to download content and then distribute it or share it online, then in all cases that would fall under direct infringement of copyright laws.

But downloading for personal amusement and use can be harmless as long as it’s intended specifically for that purpose and nothing else.

In any case, caution must be applied to avoid getting into any legal trouble. But with apps like Airy, your downloads are free of ads and copyrighted material, so there is no worry about copyright infringement in that case. It’s up to the user to be responsible and respectful about the content they consume and download.
