MP4 to MP3: what’s different
An MP4 file can carry both video and audio. Extracting MP3 keeps a portable audio copy for listening; the original video remains available.
Processing happens on your device. The sample includes a labelled synthetic tone so audio conversion can be tried immediately.
What works
- Use a source that has a real audio track.
- Choose 128 or 192 kbps for spoken content; higher settings cannot restore detail missing from the source.
- Listen to the exported result before deleting the source.
How to use it
- 1.Choose video or audio files, or try the sample with sound.

- 3.Convert, preview each completed file and download individually or as a ZIP.
Questions
Are files uploaded?
No. Media conversion happens in this browser.
What if the source has no audio?
Audio extraction reports that the source has no sound. It does not invent a silent audio track.
Will every codec work?
No. The browser must be able to decode the source and encode the selected output. Errors keep your original file available.
