- Extract music from a video for a project
- Create an audio version of a video for accessibility
- Reduce file size — MP3 is much smaller than MP4
MP4 vs MP3
MP4 is a video container — it holds video, audio, and sometimes subtitles. MP3 is audio-only. Compatible with every device, player, and platform.When you convert MP4 to MP3, you strip out the audio track and save it as a standalone file.
How to Convert MP4 to MP3 (Free, No Upload)
1. Go to the MP4 to MP3 converter
2. Upload your MP4 video file
3. The audio is extracted instantly
4. Download your MP3
No software to install. No file uploads. No waiting.
Audio Quality
The output quality depends on the audio track in the original MP4. MP3 is a lossy format, so there is minimal quality reduction — completely imperceptible for podcasts, music, and lectures.
