How to convert audio to MP3 or WAV

Choose your filesChoose one or more audio files: MP3, WAV, OGG, M4A, AAC, FLAC, Opus or WebM audio. Which ones can be read depends on your browser.

ConvertPress Convert. The files are converted one after another, and you can see the progress of each one.
DownloadDownload each file when it is ready, or all of them together in a ZIP.

Converting between compressed formats loses a little quality, so keep your originals. Files protected by DRM, such as some older music purchases, cannot be converted. If you only need one specific conversion, the M4A to MP3, FLAC to MP3 and MP3 to WAV pages explain each format.
