3
Convert and Download
Press Convert to MP3, play the preview, and download. The MP3 keeps the video's file name.
Which Videos Convert to MP3
Any video your browser can play with sound usually converts. That covers MP4 from phones and cameras, MOV from iPhones and Macs, WebM from browser recorders and most MKV files.
The converter keeps only the sound track. If a video has more than one audio language, as some MKV films do, the default track is the one converted.
| Bitrate | MP3 size per 10 minutes | Good for |
|---|---|---|
| 128 kbps | About 9.6 MB | Talks, lectures, voice |
| 192 kbps | About 14.4 MB | Music and everyday listening |
| 256 kbps | About 19.2 MB | Music on good headphones |
| 320 kbps | About 24 MB | Editing and archiving |

Video to MP3: Frequently Asked Questions
Is my video uploaded to a server?
No. Your browser reads the video and writes the MP3 on your own device. Nothing is sent to MP4toMP3.io or anyone else, and the page keeps working with Wi-Fi off once it has loaded.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. Your device's memory is the practical limit: videos up to about 45 minutes convert in one quick pass on a computer.
Which bitrate should I choose?
192 kbps suits music and most uses. 128 kbps is enough for speech and keeps files small. Choose 320 kbps for audio you will edit.
Does it work with AVI or WMV?
Not yet. Browsers cannot read AVI, WMV, FLV or 3GP on their own. Support for them needs a different engine and is planned.
Is it really free?
Yes. There is no account, no watermark and no paid plan. The conversion runs on your device, so there is no server cost.
