Convert a YouTube video to MP3.

Download a YouTube video's audio track, then convert it to MP3 in your browser.

  • Step 1: Audio-only stream link
  • Step 2: MP3 encoded in your browser
  • Limits: 30 minutes · 300 MB per file

YouTube to MP3

Two steps: get the audio track from YouTube, then convert that file to MP3 in your browser. Step one sends only the link; step two never leaves this tab.

Three pictures, nothing hidden

  1. Paste the video link and press the button. Nothing is downloaded yet — the link is only turned into an audio address.
  2. The audio opens in your browser. Right-click it and choose “Save audio as…”, or use the player’s download button.
  3. Drag the saved file into the box above. It is converted on your device, and no part of it is uploaded.

Convert to MP3
MP3 bitrate

Higher bitrates limit the extra loss from converting AAC to MP3; they cannot restore quality that is already gone.

This step never contacts a server: no file, name or duration is sent anywhere.

Compatibility and limits

This browser reports that it can decode AAC, so local conversion should work.

  • Works in Chrome and Edge 90+, Safari 15+, and Firefox on Windows and macOS.
  • Cannot decode AAC locally: Firefox on Linux, some Android WebViews and in-app browsers, and iOS before 15.
  • One file at a time, up to 30 minutes and 300 MB, because decoding happens in memory.

If the conversion step does not work on your device, the audio download above still works — you can convert that file with any desktop tool.

MP3 encoding: lamejs (LGPL-3.0), loaded only when you convert.

About this tool

What YouTube to MP3 does

Turn a YouTube video into an MP3 in two steps: download the audio track from YouTube, then convert that file to MP3 inside your browser. The conversion uploads nothing, but it is real transcoding — the file has to be downloaded first, and the browser has to be able to decode AAC locally.

  • Two steps, two different privacy rulesStep one sends only the video link to our resolver and the audio bytes come straight from YouTube. Step two never talks to a server at all.
  • Real MP3, not a renamed M4AThe output is encoded with LAME inside your browser. Some converters hand you an AAC file renamed to .mp3; this page does not.
  • Compatibility stated before you startThe page checks what your browser can decode and says so up front, including the devices where AAC decoding is missing, so a failed attempt is never a surprise.
  • Bitrate you controlChoose 128, 192 or 320 kbps. Converting AAC to MP3 is a second lossy encode, so a higher bitrate only limits the extra damage — it cannot restore quality.

Quick guide

How to use YouTube to MP3

  1. 1

    Paste the video link

    The resolver returns the audio-only stream. If the video only has a combined file, the page says so and offers that instead.

  2. 2

    Download the audio

    The file travels from YouTube to your browser; it does not pass through our servers.

  3. 3

    Convert it locally

    Drop the downloaded file back in, pick a bitrate and encode. The file never leaves your device.

FAQ

Frequently asked questions

Is this YouTube to MP3 converter free?

Yes. No account, no install and no watermark. Two limits are stated on the page: 30 minutes and 300 MB per converted file.

Why two steps instead of one click?

A browser cannot fetch a YouTube audio stream and re-encode it without cross-origin access we do not control. Doing it in one click would mean our servers handling your audio, which is exactly what we refuse to do.

Does the MP3 sound worse than the original?

Slightly, yes. YouTube delivers AAC audio and MP3 is a different lossy format, so converting re-encodes it. 320 kbps keeps the extra loss small but cannot undo it.

Which browsers cannot do the conversion?

Those without AAC decoding: Firefox on Linux, some Android WebViews and in-app browsers, and iOS before 15. The page detects this and tells you before you try.

Where do my files go?

Nowhere. Step one sends only the video link, and step two runs entirely in this tab — no upload request is made.
