You can download YouTube audio three ways: YouTube Premium's offline mode (legal, $13.99/mo), browser-based converter sites that extract audio from a video URL (varies legally), or desktop tools like yt-dlp (most reliable for power users). Each path has trade-offs across audio quality, format, legality, and convenience.
Here's the method for every device + use case, plus the formats and bitrates to know.
Method 1 — YouTube Music + Premium (legal, recommended)
YouTube Music Premium ($13.99/mo standalone or included with YouTube Premium) gives you full offline downloads of any track or video as audio. Downloads work on mobile + desktop, stay valid while subscription is active.
Open YouTube Music. Search the track or paste a YouTube video URL.
Tap the three-dot menu next to the track.
Pick "Download."
Set quality in Settings → Downloads (low/normal/high — up to 256 kbps AAC).
Downloads stay inside the YouTube Music app — playable offline, can't be exported as raw files. Best for personal listening on commute, gym, flights.
Method 2 — Online MP3 converters
Y2Mate, FLVTO, ClipConverter, OnlineVideoConverter — paste a YouTube URL, pick MP3, download the file. Quick, no install. Caveats:
Breaches YouTube ToS. Section 5(B) bans downloading. Account suspension possible if detected.
Quality cap. Most free tools cap at 128 kbps or 192 kbps MP3. Audiophile-quality (320 kbps+) usually paywalled.
Ad-heavy. Popups, redirects, fake download buttons. Use ad blocker.
Malware. Many converter sites host shady files. Never install browser extensions or executables from these sites.
Method 3 — yt-dlp (command-line, most reliable)
yt-dlp is the open-source successor to youtube-dl. Power-user tool, but free + reliable + supports highest quality formats.
yt-dlp -x --audio-format mp3 --audio-quality 0 "https://youtube.com/watch?v=..."
-x = extract audio
--audio-format mp3 = format (also: m4a, opus, flac, wav)
--audio-quality 0 = highest available (0=best, 10=worst)
Install: pip install yt-dlp on Python, or download binaries for Windows/Mac/Linux. yt-dlp pulls original audio at best available quality (typically 256 kbps M4A from YouTube).
Audio format guide
Format | Quality | File size | Best for |
|---|---|---|---|
MP3 128 kbps | OK | 1 MB / min | Casual listening |
MP3 320 kbps | High | 2.4 MB / min | Headphones, quality |
M4A 256 kbps | High | 1.9 MB / min | Apple ecosystem |
Opus 160 kbps | Very high | 1.2 MB / min | Best quality per byte |
FLAC (lossless) | Perfect | 10+ MB / min | Archive (YouTube isn't lossless source) |
Note: YouTube source audio is typically 128-256 kbps AAC. Converting to 320 kbps MP3 from a 128 kbps source doesn't add quality back — it just makes a bigger file.
Downloading audio from YouTube Shorts + music videos
Same methods work — paste the Shorts URL. Music videos sometimes have label-imposed download blocks; yt-dlp usually bypasses them, converter sites often fail.
Downloading audio on mobile
iOS: YouTube Music Premium is the cleanest option. Third-party apps usually get removed from the App Store.
Android: YouTube Music + apps like NewPipe (F-Droid) for direct downloads. Some users sideload yt-dlp via Termux.
Legality recap
Your own content: Always fine — download via YouTube Studio.
Public domain or Creative Commons: Fine — check the video's licensing.
Personal offline use, copyrighted material: Grey zone. Many countries allow under "private copying" exceptions; some don't.
Commercial use, copyrighted material: Copyright infringement everywhere. Don't.
Reuploading downloaded content: Strikes against your YouTube channel + DMCA risk.
FAQ
Best quality for YouTube audio downloads?
Original Opus or M4A (~256 kbps) via yt-dlp. Converting to higher MP3 bitrates doesn't add quality — it just inflates file size.
Can I download YouTube audio without installing software?
Yes. Browser-based converter sites work. Trade-offs: ToS breach, ad-heavy, quality capped, malware risk.
MP3 or M4A — which is better?
M4A is more efficient (better quality at smaller size). Use MP3 only if your playback device is old or doesn't support M4A. Modern phones + PCs all play M4A natively.
Can I download podcasts from YouTube?
Yes, same methods. Better option: download from the podcast's original feed (Spotify, Apple Podcasts) — original audio quality + creator support.
Can I batch-download a YouTube playlist as audio?
Yes with yt-dlp: yt-dlp -x --audio-format mp3 PLAYLIST_URL. Most online converters don't support playlists.
Next steps
For one track, an online converter works (mind ToS + malware). For ongoing library, YouTube Music Premium = legal + clean. For power users, yt-dlp is unbeatable.
