MP4 to MP3 converter
Take the sound out of an MP4 video and save it as an MP3, right here in your browser. The video is not uploaded. No sign-up and no watermark.
Your video is converted on this device. It is never uploaded.
How to convert MP4 to MP3
- Tap "Choose an MP4 video" and pick the video, or drag it onto the box.
- Pick a quality. Voice is enough for meetings and classes. Pick High for music videos.
- Tap "Convert to MP3" and keep the page open. The picture is dropped and only the sound is kept.
- Tap "Download MP3". The file goes to your Downloads folder, or to Files on iPhone.

Which quality to pick
The MP3 is much smaller than the video. For one hour of sound:
| Quality | Best for | Size per hour |
|---|---|---|
| Voice (64 kbps, mono) | Meetings, classes, talks | about 29 MB |
| Standard (128 kbps) | Podcasts, interviews | about 58 MB |
| High (192 kbps) | Music videos | about 86 MB |
Why turn a video into an MP3
A one-hour meeting video is often 500 MB to 1 GB. The same sound as an MP3 is about 30 MB. That is easy to send, keep on your phone, or listen to on the go.
This page does the work in your browser, so a private meeting video never goes to anyone's server. Only you have the file.
Turn this recording into notes
Is it a meeting, a class or an interview? Noter AI writes the transcript with speaker names, then a summary and action items. Import the MP3 in the app on iPhone or Android, or upload it in the web app.
Questions
Is the MP4 to MP3 converter free?

Does it work on iPhone?
Yes, in Safari. Pick the video from Photos or Files and keep the page open while it converts.
