About

4K YouTube to MP3 is a desktop app for saving audio from links on YouTube and other supported sites, including Vimeo, TikTok, SoundCloud, Twitch, and Bilibili. You can paste a link into the app or search for content using its built-in browser.

Features described by the publisher include:

Saving audio from individual videos, multiple links, playlists, and channels.
Exporting audio as MP3, M4A, or OGG, with an option to retain the source audio quality or adjust quality to reduce file size.
Playing converted tracks in the app’s built-in player.
Organizing playlist and channel downloads into subfolders, with track tags and .m3u playlist files.
Exporting and importing the downloads database as JSON.

To install, run brew install --cask 4k-youtube-to-mp3. The cask requires macOS 12 or later and installs the app in /Applications. After installation, open the app and paste a supported link or search in its built-in browser to get started. The publisher describes a free Starter option as well as paid plans; access to features can depend on the plan. The app is for downloading audio, not a separate video-downloader product.
