MP4 to MP3 Converter: what to know
An MP4 usually carries AAC audio next to the video. Converting MP4 to MP3 decodes that audio and re-encodes it as MP3 at the bitrate you pick, so it plays in any music player.
The conversion runs on your device with the LAME MP3 encoder compiled for the browser. The MP3's size depends only on its length and bitrate, so you know roughly what you'll get before it finishes.

Tips for the best result
- An MP3 can't sound better than the audio in the MP4; 320 kbps only helps if the source is high quality.
- To keep only part of the audio, trim the MP4 first.
