Quick answer: upload the video to an audio extractor and download the MP3 — the video track is discarded, leaving only sound. A 200 MB lecture typically compresses to a 10-20 MB audio file, small enough to email or keep on any phone.
When extracting beats keeping video
- Lectures and meetings: audio carries 100% of the information at a tenth of the size.
- Music and podcasts: MP3 plays on every device ever made, no codec surprises.
- Voice notes for sharing: small MP3s send instantly where videos stall or get recompressed — the same reason compressing videos for messaging matters.
What bitrate do you actually need?
| Content | Bitrate | 1 hour ≈ |
|---|---|---|
| Speech (lectures, calls) | 64-96 kbps mono | 25-45 MB |
| Podcasts, audiobooks | 96-128 kbps | 45-60 MB |
| Music to keep | 192-320 kbps stereo | 85-145 MB |
Extract audio in 3 steps
- Open the free video-to-MP3 converter — conversion runs in your browser, so private recordings stay private.
- Upload the video file (MP4, MOV, AVI, and more) and pick a bitrate for your use case.
- Download the MP3. No signup, no watermark, ready for any player.
What if you need silence instead?
Sometimes the goal is the opposite: keep the video, drop the sound. A video muter strips the audio track in seconds — useful for screen recordings with background noise or clips where you will add music later.

Video ToolsFrequently Asked Questions
How do I convert a video to MP3?
Upload the video to an audio extractor, choose MP3 output, and download the audio track. The video portion is discarded, so a 200 MB lecture typically becomes a 10-20 MB audio file.
Will I lose quality converting video to MP3?
MP3 is a lossy format, but spoken-word content (lectures, interviews, podcasts) is indistinguishable from the original at 128 kbps. Choose 192 kbps or higher for music you plan to keep.
What bitrate should I pick for audiobooks and lectures?
64-96 kbps mono is plenty for speech and keeps files tiny — a 2-hour lecture fits in about 50 MB. Use 128-192 kbps stereo for music.
Can I extract audio on my phone?
Yes. Browser-based extraction works in mobile Chrome and Safari: upload the video, convert, and save the MP3 straight to your device for offline listening.
