MP4 to MP3
This lesson is part of Web Developer Tools · All levels
Summary
MP4 to MP3 converter takes audio tracks from video files and stores them as standalone audio files. The process separates audio from images, then compresses it with an MP3 codec. The result is much smaller and playable on a regular music player. Since MP3 is a lossy format, it is best to convert it once from the best available source.
Key points
- MP4 is a container that can contain video and audio, whereas MP3 only contains audio.
- Audio extraction removes video tracks so the file size shrinks
- MP3 bitrate 128-192 kbps is common for music; 320 kbps gives higher quality
- Repeated lossy conversion lowers the audio quality
- Make sure the audio track is selected correctly if the video has multiple languages
