Whether you need audio from a Zoom recording, a downloaded lecture, or a concert video, extracting the audio track as MP3 is one of the most common media tasks. With 79,000 monthly searches for "video to mp3," millions of people need this conversion every month.

MiOffice handles this entirely in your browser. FFmpeg WebAssembly decodes the video container, extracts the audio stream, and encodes it as MP3 -- all without uploading a single byte to any server.

Why Extract Audio Instead of Recording?

  • --Podcast repurposing: Turn video interviews into podcast episodes without re-recording.
  • --Storage savings: A 10-minute 1080p video at 200 MB becomes a 14 MB MP3 -- a 93% reduction.
  • --Mobile listening: Convert lectures or conferences to MP3 for listening on the go.
  • --Transcription prep: Audio-only files process faster and cheaper in transcription services.

Pro Tip: Normalize After Extraction

Audio from video recordings often has inconsistent volume levels. After extracting, run the MP3 through the audio normalizer to even out volume, then use MP3 Cutter to trim unwanted sections.

Privacy First

Videos contain sensitive content -- meetings, personal moments, proprietary information. MiOffice processes everything locally with FFmpeg WebAssembly. Your files stay on your device. Verify by checking the Network tab in your browser's developer tools during conversion.
