YouTube Audio Downloader

This tool pulls the audio track out of a YouTube video and gives it to you as a clean MP3, without downloading the video part at all. That makes it faster and far lighter than saving the full video: an hour of audio is ~56 MB at 128kbps versus over a gigabyte for the same hour in HD video.

YouTube stores audio as its own stream (AAC or Opus) alongside the video. We fetch that original stream directly and convert it exactly once with FFmpeg at your chosen bitrate, no screen recording, no playing-and-capturing, no stacked re-compression. The result is as close to the source quality as an MP3 can be. For editing work where you want no lossy step at all, there is a lossless WAV export, though it cannot restore detail the source never had. The full technical background is in our guide on extracting audio from YouTube videos.

• Podcasts and interviews published only as video, listen in any podcast or music app.
• Lectures, courses and tutorials, study offline without the screen on, saving battery and data.
• Conference talks and sermons. The picture usually adds nothing; the audio is everything.
• Your own videos, recover the audio master from your channel when the original project file is gone.

Most of this page is about spoken audio, where the extraction is straightforward and almost any bitrate will do. Music is the harder case, and it is worth treating separately.

YouTube is the largest music library in existence, and a great deal of what sits on it exists nowhere else: live sessions, radio takes, covers, remixes, full DJ sets, and uploads artists publish themselves. Four situations come up again and again:

• Live versions and rare tracks. Concerts, sessions and bootlegs that never reached a streaming service. This is the classic reason people come looking.
• Your own uploads. Pulling the master back off your own channel when the project file is long gone. Nothing about this is legally awkward, and it is the case we see most from creators.
• Creative Commons and royalty-free music. Building a legal library for videos, streams and games. YouTube search can filter by licence, so you can find this material deliberately rather than hoping.
• Albums and long mixes. Hour-long uploads convert without trouble, though on a very long one 256kbps is the safer choice if a 320kbps job times out.

One honest limit, since it is the thing most converter sites quietly avoid saying: no tool can make a song sound better than YouTube's copy of it. The source is roughly 128 to 160kbps AAC or Opus, and a high MP3 bitrate preserves what is there rather than adding anything. That is still worth having, because a low bitrate would throw some of it away, but "studio quality" from a YouTube link is marketing rather than engineering.

Commercial music is copyrighted almost everywhere, and downloading it to avoid paying for a streaming subscription is precisely what copyright law exists to prevent. It is better to say that plainly than to bury it in a disclaimer nobody reads.

What is clearly fine: tracks you made, music released under Creative Commons, recordings in the public domain, and anything where the artist has said you may keep a copy. Plenty of musicians say exactly that in their video descriptions. The details vary by country and are not always intuitive, so our legality explainer works through the cases properly, including how to check a licence in about twenty seconds.

Choose 128kbps for anything spoken. Speech is fully transparent there. Choose 256-320kbps for music, or go straight to the 320kbps converter, which defaults to that bitrate and shows you what the source audio actually contains. Choose 64kbps only when storage is tight (audiobooks on an old phone, for example). Higher bitrates protect quality during conversion but cannot exceed what the source contains.

Extract only audio you have the right to keep, your own uploads, licensed content, or Creative Commons material. This educational tool is not affiliated with YouTube.
