Convert MP4 to MP3
Keep just the audio of an MP4: a song, a talk or a voice message. Converted on your device in seconds.
Your file stays on your device. Nothing is uploaded.
How to convert MP4 to MP3
- Choose your MP4 file.
- Pick a quality: 192 kbps suits most music.
- Press "Convert to MP3", listen to the preview and download.
Which quality should I pick?
- 128 kbps: about 1 MB per minute. Fine for speech, lectures and podcasts.
- 192 kbps: about 1.4 MB per minute. Good for music; most people can’t tell it from the original.
- 320 kbps: about 2.4 MB per minute. The highest quality MP3 allows.
Your file never leaves your device
The conversion runs in your browser. Nothing is uploaded, so it is fast even on a slow connection, and nobody else gets a copy.
Frequently asked questions
Does the MP3 lose quality?
MP3 is a compressed format, so it is re-encoded. At 192 kbps or 320 kbps the difference is very hard to hear.
Is it free? Do I need an account?
It is free, with no sign-up and no limit on how many files you convert.
Does it work on iPhone and Android?
Yes, in Safari and Chrome. Files up to 500 MB work on phones; on a computer you can use files up to 1 or 2 GB.
Can I download music from YouTube with this?
No. It converts files that are already on your device, like videos you recorded or were sent.
