What happens when you convert MP4 to MP3
An MP4 file is a container: it holds a video track and, usually, an AAC audio track side by side. Converting MP4 to MP3 means throwing the picture away and keeping only the sound, re-encoded as MP3 so it plays on any phone, car stereo or podcast app.
This is handy for recorded lectures and webinars you want to listen to on a walk, Zoom or Teams recordings you need to transcribe, music videos you made yourself, and screen recordings where only the narration matters. iPhone videos (MOV) and WebM screen captures work the same way.
For speech, 128 kbps is plenty: an hour-long lecture comes out at roughly 55 MB. For music, choose 192 or 320 kbps. Because the conversion runs in your browser, a long video can take a minute on an older laptop, but it never has to upload first.
Only need part of the soundtrack? Convert first, then trim the MP3 with the audio cutter.
