The fastest way to get audio from YouTube on Mac

The simplest method is to use a dedicated audio-download tool that works directly in your browser. yt-dlp is free, runs from the command line, and downloads the audio file to your Mac in a few seconds. If you prefer not to use the terminal, 4K Video Downloader has a Mac version with a graphical interface — you paste the YouTube link, choose audio-only, and click download.

Both tools pull the audio stream directly from YouTube and save it as an MP3 or M4A file to your Downloads folder. Neither requires signing up for an account or installing browser extensions that slow down your machine. The trade-off is that 4K Video Downloader costs money after a trial period, while yt-dlp is free but requires typing commands.

Key Takeaways

  • yt-dlp is free and works from the Mac terminal to download audio in seconds, but requires basic command-line knowledge.
  • 4K Video Downloader has a point-and-click interface on Mac and handles YouTube links without the terminal, though it costs money after the trial.
  • Downloaded audio files land in your Downloads folder as MP3 or M4A files that play in Music, Spotify, or any media player.
  • Browser extensions and online converter websites are slower, less reliable, and often inject ads into the download process.

Using yt-dlp from the terminal

yt-dlp is a command-line tool that downloads audio faster than any graphical tool because it has no interface overhead. First, install Homebrew if you do not have it — open Terminal (find it in Applications > Utilities) and paste this line, then press Enter:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Once Homebrew finishes, install yt-dlp by typing this into Terminal and pressing Enter:

brew install yt-dlp

Now you can download audio from any YouTube video. Copy the YouTube link, go back to Terminal, and type this command (replace the URL with your actual link):

yt-dlp -x --audio-format mp3 "https://www.youtube.com/watch?v=VIDEO_ID_HERE"

The -x flag tells yt-dlp to extract audio only, and --audio-format mp3 saves it as an MP3 file. The file appears in your Downloads folder within seconds. If you want M4A format instead (which takes less disk space), replace mp3 with m4a.

Using 4K Video Downloader on Mac

4K Video Downloader is a graphical application that does not require the terminal. Download it from the official website (search "4K Video Downloader Mac"), install it like any other Mac app, and launch it. The first 30 days are free; after that, a license costs money.

Open the app and you will see a large text box labeled "Paste Link Here". Go to YouTube, find the video you want, copy the URL from the address bar, and paste it into that box. Click the Download button below.

A window appears with format options. Look for Audio in the left sidebar and select it. Choose MP3 or M4A from the dropdown, then click Download again. The file saves to your Downloads folder. The whole process takes about the same time as yt-dlp, but you never touch the terminal.

What to do if the download fails

YouTube occasionally changes how it serves audio, which can break downloaders temporarily. If yt-dlp stops working, update it by typing this in Terminal:

brew upgrade yt-dlp

If 4K Video Downloader fails, check that you are using the latest version — open the app, go to the menu, and look for an update option. Both tools are maintained by their creators and usually get fixed within days of a YouTube change.

If a specific video will not download, it may be age-restricted, private, or region-locked. YouTube's own restrictions prevent any tool from downloading those videos, and there is no workaround.

Choosing between MP3 and M4A format

MP3 is the older standard and plays on every device and media player. It takes up more disk space than newer formats but is the safest choice if you plan to move the file between devices or share it.

M4A is Apple's format and uses better compression, so the same audio takes up about 30 percent less space. It plays in Music, iTunes, and most modern apps, but some older devices and non-Apple software may not recognize it. If you only use Mac and iPhone, M4A is the better choice.

Playing and organizing your downloaded files

Once the download finishes, the audio file sits in your Downloads folder. Double-click it to open it in Music (or iTunes on older Macs), and it plays immediately. To keep your files organized, create a folder called "Downloaded Audio" in your Music folder and drag the files there.

If you want to add the audio to your Music library permanently, open Music, go to File > Import, and select the file. It then appears in your library alongside your other music. You can create playlists, add artwork, and edit the song title and artist name just like any other track.

Why not use browser extensions or online converters

Browser extensions that claim to download YouTube audio often slow down your browser, inject ads into web pages, or ask for permissions they do not need. Online converter websites (the kind where you paste a link and click a button) are even slower because they process the video on their servers instead of your Mac, and many display aggressive ads or ask you to download software you do not want.

yt-dlp and 4K Video Downloader are faster, more reliable, and do not clutter your system. They also work offline once installed, so you do not depend on a website staying online or a company keeping the service running.

Frequently Asked Questions

Is it legal to download audio from YouTube?

That depends on the video and your location. If the video is music the creator owns or has permission to distribute, downloading it is usually against YouTube's terms of service. If it is a podcast, lecture, or other content the creator has said you can download, it may be allowed. Check the video description or contact the creator if you are unsure.

Can I download audio from a YouTube playlist?

Yes. With yt-dlp, you can download an entire playlist by pasting the playlist URL instead of a single video URL. The command is the same. 4K Video Downloader also supports playlists — paste the playlist link and it shows all videos in the list, then you can select which ones to download.

Why is my download so slow?

YouTube throttles downloads to prevent abuse, so very large files or multiple simultaneous downloads may take longer. If you are downloading a two-hour podcast, expect it to take a few minutes. If a short song takes more than 30 seconds, your internet connection may be the bottleneck — try again later or check your Wi-Fi signal.

What if I want to edit the audio after downloading?

Use Audacity, which is free and runs on Mac. Open Audacity, go to File > Open, and select your downloaded MP3 or M4A file. You can trim, cut, adjust volume, add effects, or export it in a different format. Audacity is more powerful than you need for basic edits but has no cost.

Can I download video as well as audio?

Yes. Both yt-dlp and 4K Video Downloader download video files too — just skip the audio-only step and choose a video format instead. yt-dlp downloads video with this command: yt-dlp "https://www.youtube.com/watch?v=VIDEO_ID" (without the -x flag). The file saves as an MP4.
