About this tool

This free online audio converter changes the format and encoding of a file — MP3, WAV, FLAC, OGG or M4A — with control over bitrate, sample rate and channel layout from one clean settings plate.

Conversion is performed by your own browser, so even long files never leave your machine and there is no size limit imposed by an upload form.
