Is this a YouTube downloader?

No. This tool converts files that are already on your device. Please download videos only when you have the rights or permission to do so.

Which bitrate should I choose?

192 kbps is a great balance for most audio. Choose 320 kbps for music you care about and 128 kbps when file size matters more, like for voice recordings.

Does my file leave my device?

No. The conversion runs in your browser with FFmpeg, so your file is processed locally and never uploaded.

Can I convert from a phone?

Yes, the tool works fully on mobile browsers. On iPhone, export videos to Files first if the upload picker limits you.

About this tool

Turn any video into an MP3 audio file in your browser. Perfect for pulling a song out of a music video, saving the audio from a lecture recording, converting a voice memo, or building a personal podcast collection. Choose your bitrate — 128, 192, or 320 kbps — to balance file size against audio fidelity. The conversion runs locally on your device with the FFmpeg engine, so your file is never uploaded anywhere. Video, audio, and screencast files are all supported as input.
