How to convert MP4 to MP3

Upload your MP4 file above.

Open Advanced settings only if you need trimming, resolution, bitrate, sample rate or a custom filename.
Start the conversion and download the finished file when it is ready.

Before you convert

Re-encoding can change quality and file size even when the extension stays familiar. Repeated lossy conversion cannot restore detail removed from the original source.

Changing a container or codec cannot recreate quality already missing from the source, so keep an important original when possible.
