Max file size: ~2 GB (memory permitting)
Why use this YouTube to MP3?
- Stream-copy preserves the original audio bitrate when the source is already AAC / Opus.
- For non-MP3 sources (most YouTube videos), the converter re-encodes to MP3 192 kbps (transparent for music).
- No upload — keeps your local YouTube downloads private.
- Output is a clean MP3 with no watermark, ad, or branding.
How to use it
Download the YouTube video
Use a browser extension or yt-dlp locally — we don't fetch from URLs to keep things private.
Drop the file into the extractor
MP4, WebM (the two YouTube formats) both work.
Pick MP3 192 kbps and download
Output is a tagged MP3 ready for any music app.
What to watch out for
| Extraction does not improve anything | The audio in a downloaded video is already compressed. Pulling it out and re-encoding cannot add back what the original encode discarded. |
|---|---|
| 192 kbps is plenty for speech | Podcasts, lectures and interviews sound the same at 192 as at 320, at two thirds the size. Music is where the higher rate is worth it. |
| Download it first | This tool works on a file, not a URL. Fetching from a URL server-side is what gets those sites shut down, which is why it is not offered. |
FAQ
Can I extract audio from a YouTube URL directly?
No — we don't fetch from URLs. Download the video first using your preferred local tool, then drop the file here for audio extraction.
Will the audio sound the same as YouTube?
Yes — at 192 kbps MP3, the result is sonically transparent for music. For voice-only content, 128 kbps is often sufficient.
Does this run in my browser?
Yes — the tool uses FFmpeg compiled to WebAssembly. Your file never uploads to a server, never leaves your device, and there is no signup or watermark.
