Convert audio to WAV for editing or compatibility

Some editors, old hardware, and voice tools only accept WAV. Decode any audio file your browser can play and save it as uncompressed PCM.

The job

MP3 and AAC are delivery formats — lossy and sometimes rejected by editors, samplers, or game engines that want plain PCM. WAV is uncompressed audio that almost everything reads.

Convert the file

Choose the audio file, run the conversion, and download the WAV. The result is 16-bit PCM at the source's sample rate; stereo is preserved and multi-channel audio is downmixed to stereo.

Converting does not restore quality lost to MP3 compression — it only changes the container.
WAV files are much larger than MP3: roughly 10 MB per minute of stereo audio.

Worked example

A 3-minute stereo MP3 decodes to a WAV of about 30 MB at 44.1 kHz — large but lossless to hand to an editor. A 10-minute cap and 256 MB output limit apply.

When the file won't convert

Decoding uses the browser's own decoders, so anything the browser can't play (some WMA, exotic codecs, DRM-protected files) fails with a decode error rather than a partial file.

Everything happens locally — the audio never leaves the device.
To shorten a recording instead of changing format, use the audio trimmer.
