You can save audio from YouTube as an MP3 file in 30 seconds using a free browser-based converter. Three methods work reliably: a third-party converter (fastest), YouTube Premium offline (legal, audio-only mode), or yt-dlp on desktop (most flexible). Each has different use cases and legal weight.
Here's the actual workflow for each, the tools we've tested, and the legal lines you shouldn't cross.
How to save audio from YouTube — three methods
Method 1: Browser-based YouTube-to-MP3 converter
Fastest. Free. No signup.
- Copy the YouTube video URL.
- Go to a converter site (see ranked list below).
- Paste the URL.
- Pick MP3 as the output format.
- Pick bitrate (128 kbps is fine; 320 kbps for music).
- Download. The MP3 lands in your Downloads folder.
Method 2: YouTube Premium audio-only mode
Fully legal. Available with a YouTube Premium subscription ($14/mo).
- Open the YouTube app.
- Play a video. Tap the three dots → "Audio mode" (Premium only).
- Audio plays in the background. Download the video for offline; audio plays even when screen is locked.
You don't get an MP3 file you can use elsewhere, but you can listen offline inside the YouTube app.
Method 3: yt-dlp (command line)
For technical users. Open-source, free, most reliable.
- Install yt-dlp (pip install yt-dlp on Mac/Linux, or download Windows binary).
- Open terminal.
- Run:
yt-dlp -x --audio-format mp3 [YOUTUBE-URL] - The MP3 file lands in your current directory.
No ads, no nag screens, supports playlists and channels in one command.

Audio quality and file sizes
| Bitrate | Quality | File size (per 10 min) |
|---|---|---|
| 96 kbps | Low (voice acceptable) | ~7 MB |
| 128 kbps | Standard (default) | ~10 MB |
| 192 kbps | Good (most music) | ~14 MB |
| 256 kbps | High (music + ambience) | ~19 MB |
| 320 kbps | Maximum MP3 | ~24 MB |
YouTube's source audio is typically 128 kbps AAC. Converters above 128 kbps add file size without adding actual quality.
Is saving YouTube audio legal?
Same rules as full YouTube video downloads:
- YouTube Premium offline: Fully legal. You're paying for the right.
- Personal use via converter: Legal grey area in most countries. Technically against YouTube's Terms of Service.
- Re-upload to another platform: Copyright violation. Don't.
- Use in your own content (podcast, video): Almost always a copyright violation unless the audio is Creative Commons.
Safe rule: download for personal listening, never reuse commercially.
Saving podcasts hosted on YouTube
Many podcasters publish episodes on YouTube. Use cases for saving the audio:
- Offline listening on a phone without YouTube Premium
- Speeding up playback in a dedicated podcast app
- Auto-transcribing using Whisper or Otter.ai
For these use cases, MP3 conversion at 96-128 kbps is plenty. Music needs higher bitrates; voice doesn't.
Batch downloading audio (playlists or channels)
For backing up large amounts of audio:
- yt-dlp:
yt-dlp -x --audio-format mp3 [PLAYLIST-URL]— downloads every video in a playlist as MP3. - 4K YouTube to MP3: Paste a channel URL, downloads all videos as MP3.
- SnapDownloader: Built-in batch support.
Saving YouTube audio on mobile
- iOS: Use a browser-based converter, save the MP3 to the Files app, then move to Apple Music or your podcast app.
- Android: Browser-based converters save directly to the Downloads folder. Some Android apps (Newpipe) download audio natively.
Converters to avoid
- Anything requiring YouTube login
- Tools that push desktop installers with adware
- Sites demanding cryptocurrency payment
- Browser extensions requesting "all sites" access
