How to convert MP4 to MP3
- Add your MP4 videos. Drag them onto the box above or click to browse. You can add several at once.
- Pick a quality. 192 kbps suits most uses; choose 320 kbps for the best quality or 128 kbps for smaller files.
- Download. Each MP3 gets its own download button as soon as it’s ready.
What is MP4?
MP4 is the most common video format — phone recordings, screen captures, exported edits and most downloaded videos use it. Often you only need the sound: a lecture to listen to on the go, a live performance you filmed, or the audio of a talk. Converting MP4 to MP3 keeps just the audio track and drops the video, so the file is a fraction of the size.
Tips
- Because nothing is uploaded, even a large MP4 converts quickly — the speed depends only on your device.
- Phone videos usually have 128–256 kbps audio, so 192 kbps captures everything.
- Only convert videos you made yourself or have permission to use.
MP4 to MP3: questions
Can I convert videos recorded on my phone?
Yes. Pick the video from your gallery or files and the converter keeps just the audio.
Is there a size limit?
Files up to 1 GB are accepted. Large videos need enough free memory on your device, so very long videos work best on a computer.
Can I paste a YouTube link?
No — this tool only converts files already on your device.
Are my files uploaded?
No. Anything to MP3 converts MP4 to MP3 inside your browser, so your files never leave your device.
