MP3 is converted to WAV on your device. The result is uncompressed PCM WAV, so the file is usually larger than the source.

This mode is for editor compatibility and further processing. It does not restore quality already lost during MP3 compression.

How to use it

Add an MP3 file and process. The browser decodes the audio locally and saves an uncompressed WAV file.

Recommended settings

WAV is usually much larger than MP3, but it opens in editors and is convenient for later processing. It will not improve the original MP3 quality.

Privacy

Your files are not uploaded to a server. The editor runs in your browser with local libraries from this site.

Limits

Large images can take longer on phones. If the browser slows down, process fewer files at once or choose a smaller output format.
