4K YouTube to MP3

About

4K YouTube to MP3 converts videos from YouTube, Vimeo, TikTok, SoundCloud, Twitch, Bilibili, and other sites into audio files. Paste a link into the app or search for content in its built-in browser, and the conversion happens quickly. You can save the results as MP3, M4A, or OGG, download full playlists and channels in one go, and keep the original audio quality or reduce file size. Downloads can be played in the built-in music player or transferred to mobile devices, and the app includes an AI Audio Studio for extracting or removing vocals and reducing background noise.

The app also offers organization and access tools. Saved playlists and channels go into automatically created subfolders, audio tags are generated from track names, and .m3u files are created for playlists. Users can download their own private YouTube playlists, such as Watch Later and Liked videos, and export or import their downloads database as a JSON file. A download speed control adjusts performance to suit slow connections, and an in-app proxy setting is available for accessing content restricted by a network. A free Starter plan is available, with paid Lite, Personal, and Pro licenses for extended and commercial use.
