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.

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.
