Why MP3 still wins for audio-only

MP3 plays everywhere. Keeping a full MP4 for audio wastes space and battery. Extract once, listen offline.

Drop one or more MP4 files.
Convert — first run may load the browser media engine.
Download the MP3 (or ZIP for batches).

Tips

Trim silence first with Trim Video if the file is long.
