How it works
01
Paste the link
Any public YouTube URL, including the short youtu.be form and phone links with tracking parameters.
02
Pick a format
MP3 for anything that plays everywhere. Best keeps the original audio codec with no re-encode. WAV for an editor.
03
Download
The file saves straight to your device. No second click, no waiting room, no countdown.

What you get
Best means the stream untouched
Pick Best and you get the audio exactly as YouTube served it, with no re-encode and no second generation of loss. That is the honest quality ceiling for any converter.
MP3, OGG or uncompressed WAV
MP3 for listening and for anything with a size limit. WAV when the file is going into an editor.
Nothing installed
Runs in the browser. No app, no sign-up, nothing offered on the way out.
Nothing kept
Nothing is stored on our side after the download. No library, no account.

What you actually get from a YouTube video
A YouTube video is not one file. Video and audio are served as separate streams, and an extraction tool asks for the audio stream on its own. The file is repackaged, or re-encoded into the format you asked for, and handed to you. Nothing is remastered, cleaned up or restored on the way through.
That sets a ceiling no tool in this category can move. The audio you get can be as good as the stream YouTube served, and no better. If the uploader recorded on a laptop mic, or exported a heavily compressed file before they hit publish, that's what comes out the other end.
YouTube serves audio at a handful of quality tiers, and which one you get depends on the video and the codec. The tier belongs to the video, not to the tool. That's why the Best option exists here: it hands you the served stream untouched, which is the most any converter can honestly offer.
Bitrate, and why 320 kbps is not a quality dial
A bitrate is how much data per second an encoder is allowed to spend. 320 kbps is the top of the MP3 specification, and it's the number this whole category advertises, which is why almost everyone reads it as a quality setting. It isn't. It's a ceiling on the encoder, not a description of the audio.
Here's what happens when a converter promises it. The tool takes the audio YouTube served, already compressed and already lossy, decodes it, and re-encodes it with a 320 kbps budget. The re-encode can't invent detail the source threw away. Past the point where the encoder carries everything the source still has, extra bits do nothing, and on a modest source that point arrives well before 320.
So a 320 kbps export from a lower-quality source is a bigger file, not better audio: roughly two and a half times the size of a 128 kbps export of the same thing, for audio you won't tell apart. A page promising 320 kbps audio from YouTube is promising a 320 kbps container. What goes inside was decided upstream.
If you want the most the source can give, pick Best and the stream is passed through untouched. Pick MP3 when the file has to play everywhere.
WAV, and what lossless does and doesn't buy you
WAV is uncompressed. Every sample is stored as it was handed to the encoder, so nothing is discarded at the point of export. That's what lossless means, and it's a genuine property of the format.
What it doesn't mean is that the audio is lossless. Copying a lossy source losslessly gives you a perfect copy of a file that already had detail removed. The WAV is faithful to what YouTube served, and what YouTube served was compressed. Lossless describes the export, not the recording. Converting to WAV recovers nothing, and a WAV of a YouTube video is not a master.
The real reason to use it is editing. Every MP3 encode loses a little and the loss stacks. One pass is usually inaudible. Cutting, layering, pitching and re-exporting three or four times over is not. If the file is going into an editor, take the WAV, do the work, and encode once at the end.
If you're only going to listen to it, take the MP3. WAV is ten times the size for audio that sounds identical, has no room for artwork or track information, and some phones and car stereos handle it badly.
When the audio needs to be yours
Extraction has a limit that has nothing to do with audio quality: the track belongs to whoever made it. Put it under a video and copyright systems will usually identify it, and the outcome ranges from the video being muted or blocked to the revenue going somewhere else. That's the thing people find out after the upload.
This is where Unsora does something no converter can. It plugs into ChatGPT, Claude and other assistants over MCP, so you describe the music or the voiceover you want in plain language and it's generated in the same chat. Original audio, made for your video, that no rights system has a claim on. If you need a track for something you're making rather than a copy of something you like, generating it is the shorter route.
Audio is two of the eleven tools on one subscription. The rest are video and image generation, AI influencers, clipping, subtitles, upscaling, thumbnails and social scheduling. From $19/mo for 500 credits, 3-day trial on every tier. This converter stays free either way.

Honest limits
What this tool does
- Extracts the audio from a public YouTube video as MP3, OGG or WAV
- Passes the original stream through untouched when you pick Best
- Names the file after the video, not a video ID
- Handles videos up to 3 hours, which covers most podcasts and lectures
- Runs in any browser, with no account, installer or extension
- Keeps nothing on our side after the download
What it doesn't do
- It won't open private or unlisted videos. Those need permission this tool isn't signed in to have.
- It won't touch paid, rented or members-only content. Anything behind a paywall is out of scope.
- It doesn't circumvent copy protection. Where content is protected by technological measures, this tool stops. No setting changes that.
- It can't improve the audio. The source stream is the ceiling. A converter promising better-than-source audio is describing a file size.
- A high bitrate doesn't make a low-quality source sound better. It makes the file bigger.
- WAV doesn't restore anything. A lossless copy of a lossy source. Good for editing, pointless for listening.
- It doesn't remove noise, normalise levels or master anything. You get the track as it came.
- It doesn't do playlists or channels in bulk. One video at a time.
- It doesn't clear any rights for you. Extracting audio is not permission to publish it.
Checklist
What to check before you use any YouTube to MP3 converter
Free converters are one of the most aggressively monetised categories on the web, and the monetisation is usually not the converter. Six things worth checking on any of them:
01
Does one click do one thing?
Press convert and count what happens. A new tab, a background window, a redirect, or a page reloading into an offer is the tool telling you what it's for.
02
Is the download button the real one?
The common pattern is several identical-looking buttons where the biggest and greenest is an advert. If you have to look carefully to find the real one, that ambiguity was designed.
03
Does it want to install something?
Nothing about extracting audio requires an app, an extension, a download manager or a codec pack. When a web converter routes you to an installer, the installer is the product.
04
Does it explain the bitrate menu or just show one?
A list running from 64 to 320 kbps with no explanation is decoration. What matters is what the source stream was, because that decides whether the options differ at all.
05
Does it say what happens to your file?
Converted files sit on somebody's server unless someone deletes them. A tool silent on retention hasn't told you it isn't keeping yours.
06
Does it ask for an account?
Converting a link needs no identity. An email requirement on a free converter is a list-building step wearing a feature's clothes.
Need audio you can publish?
An extraction gives you a copy of a recording somebody else owns. That works until a platform matches it.
Unsora makes the audio instead. Describe the track or voiceover inside ChatGPT or Claude and it comes back original, so the sound under your video is yours. Eleven creator tools in one subscription, from $19/mo with 500 credits, and every plan has a 3-day free trial. The converter is free and stays free.

Common questions
Is this free, and do I need to install anything?
Free, with no account, no email and no daily cap. It runs in the browser, so there's no app, extension or download manager, and you won't be offered one.
Which format should I pick?
MP3 if the file has to play everywhere. Best if you want the original audio codec untouched, with no re-encode. WAV only if the file is going into an editor.
Why doesn't a higher bitrate sound better?
The source is the limit, not the setting. Re-encoding higher can't add back detail compressed away before upload, so past a point the extra bits describe nothing new and you get a larger file that sounds the same.
Should I choose WAV instead?
Only if you're editing. WAV avoids stacking another generation of MP3 loss when you cut and re-export. It doesn't improve the audio, and for listening it's ten times the size for no audible gain.
Is a WAV from YouTube lossless?
The file is. The audio isn't. WAV stores what it's given without discarding anything, and what it's given is already a compressed stream. A perfect copy of a lossy source.
Can I convert a whole playlist or channel?
No. One video at a time, deliberately.
Can I use it on private, unlisted or members-only videos?
No. Private and unlisted videos need permission this tool doesn't have, and anything behind a membership, rental or purchase is out of scope.
Is converting YouTube to MP3 legal?
It depends on the content and where you are, and a tool page can't answer that for your situation. Two things are true regardless: YouTube's Terms of Service don't permit downloading outside its own offline feature, and the recording is owned by whoever made it, so extracting a track is not permission to publish it.
Can I use the audio in my own video?
Only if you hold the rights. Copyright systems match audio automatically, and a match on a track you don't own can mute the video, block it or send the revenue elsewhere. If you need audio you can publish freely, generating original music is cleaner.
Does it work on a phone?
Yes, in the mobile browser. On iOS the file lands in Files or Downloads, not the music library, so you'll move it yourself.
Why did my link fail?
Usually the video is private, age-restricted, region-blocked, members-only or removed. Live streams won't convert until they've ended. If a public video fails, check the URL didn't get truncated when you copied it.
Is there a length limit?
Videos up to 3 hours are supported, which covers most podcasts and full-length lectures. Anything longer is refused rather than left to stall.
What happens to my file afterwards?
Nothing is kept on our side after your download, and there's no account for it to be stored against.
Can I get the video as well?
This page does audio only. For the video file, use the YouTube video downloader.
