How to turn a YouTube video into an audio file
You turn a YouTube video into an audio file by pasting its URL into a web converter and saving the output as MP3, M4A, or another audio format—the video track gets dropped in the process. YouTube serves both streams together; a converter splits them server-side so you end up with something your music app or editor can open. I use this for conference talks (slides irrelevant), ambient loops, and songs where I only need the file on my phone. This guide covers format choice, device-specific saves, and the video-first workaround when direct conversion acts up.

What you get when you "turn video into audio"
Searching how to turn a youtube video into an audio file means you want a .mp3, .m4a, .wav, or similar—not an MP4 with a black screen or a screen recording. The result is a single audio track encoded from whatever YouTube streamed. You're not upgrading studio quality; you're repackaging what's already there.
| Starting point | You end up with | Typical use |
|---|---|---|
| Music video | MP3/M4A | Offline listening |
| Podcast upload | MP3 128 kbps | Commute playback |
| Tutorial | MP3 or M4A | Listen without watching |
| Live DJ set | MP3 192 kbps+ | Phone library (rights permitting) |

Pick your audio format first
Don't convert twice because you picked wrong.
| Format | Opens in | Size (5 min, music) | Notes |
|---|---|---|---|
| MP3 | Everything | ~7 MB @ 192 kbps | Default choice |
| M4A (AAC) | Apple Music, most Android | ~6–8 MB | Slightly better per MB |
| WAV | Audacity, Logic, Premiere | 50+ MB | Large; source still lossy |
| OGG | Some Android apps, Firefox | ~5–6 MB | Less common on iPhone |
Rule of thumb: MP3 for sharing. M4A if you live in Apple Music. WAV only if your editor demands it and you accept the file size.
Method 1: Direct YouTube → audio file
Fastest route when the video is public and under ~2 hours.
- Copy the full YouTube URL (including
?v=or Shorts link). - Open YouTube to MP3 or the YouTube converter hub for M4A.
- Paste. Select format and bitrate.
- Convert. Download when ready.
Windows: File → Downloads\filename.mp3. Right-click → "Show in folder" if you lose it.
Mac: Downloads folder or Desktop depending on browser settings.
Android: Downloads app or notification shade.
iPhone: Safari downloads to a temporary list—tap the file, then Share → Save to Files (pick iCloud or On My iPhone). It won't auto-appear in Apple Music without import.
Processing a four-minute pop song took me about 40 seconds last time I tested on fiber. A 90-minute webinar might fail—those aren't what lightweight converters target.
Method 2: Video file first, audio second
Sometimes direct audio conversion errors out. Or you already downloaded MP4 for a project and now want sound only.
- Save video: YouTube to MP4.
- Upload the MP4 to extract audio from video.
- Pick output format. Download.
Extra step, but you keep the video if you need screenshots later. You can also trim dead air with the audio trimmer after extraction.
Phone vs computer: where files land
Computers give you a clear path. Drag MP3 into Spotify local files (desktop), iTunes/Music, or VLC.
Phones need one more tap. Android often puts files in Download/ visible to file managers. iOS hides browser downloads unless you push them to Files—then open Files → long-press → Share to Music if your workflow allows.
If you're phone-first, our music to your phone guide walks through iOS and Android quirks in more detail.
Quality expectations (be realistic)
YouTube re-encodes uploads. A 1080p music video might stream audio at 128–160 kbps equivalent regardless of what the artist uploaded. Choosing 320 kbps MP3 on the converter doesn't restore lost data—it just makes a bigger file of the same information.
For speech, 128 kbps is plenty. For music you care about, 192 kbps is the practical ceiling unless you have a lossless source elsewhere.
What won't convert
- Private or unlisted links you can't open logged out
- Age-restricted videos without passing the sign-in check
- Premiere/rental content with DRM
- Deleted videos
- Copyright-blocked uploads in your region
"Sign in to confirm you're not a bot" on YouTube itself is a separate issue—fix that in the browser first, then retry the converter.
Legal and ToS reminder
Turning videos into audio files for content you don't own or lack permission to download may violate YouTube's Terms of Service. Personal backups of your own channel, CC-licensed material, and creator-approved downloads are the intended use cases.
Conclusion
Choose MP3 or M4A, paste the YouTube URL, convert, save. Use the video-then-extract path when direct conversion fails or you want both formats. Match bitrate to content—128 for speech, 192 for music.
