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 never leave your device. Verify by checking the Network tab in your browser's developer tools during conversion.
