How to convert MP4 to MP3
Three steps to an MP3 file
11. Upload your MP4
Click “Upload” or drag your video onto the page. Files up to 100 MB accepted.
22. Choose MP3 settings
MP3 is pre-selected. Optionally set bitrate (128, 192, 256 or 320 kbps) or keep source quality, then hit “Convert”.
33. Download the MP3
Conversion finishes in seconds. Save the audio file to your device.

Adjustable bitrate
Pick anywhere from 64 to 320 kbps. Higher bitrate keeps more detail in music; lower bitrate saves space for voice recordings.
