Convert one audio file to the format you need

Choose an input and select MP3, WAV, or M4A as the output. This is useful when a player, editing application, or sharing workflow requires a different format. The converted audio can be previewed before download.

Choosing MP3, WAV, or M4A

MP3 offers broad compatibility and relatively small files. WAV is commonly uncompressed and convenient for editing, but takes more space. M4A typically carries efficient AAC audio. Converting to a larger container does not automatically improve the source.

What re-encoding means

Converting lossy MP3 or M4A audio cannot restore information already removed, and another lossy encode may introduce small changes. Keep valuable originals and listen to the result. Common MP3, WAV, M4A, and AAC inputs are converted on your device, not a server.
