How do I convert MP4 to WAV?

Upload your MP4 file using the box above, confirm WAV as the output format, then select Convert. The converted file is ready to download as soon as processing finishes — usually in a few seconds.

Is converting MP4 to WAV free?

Yes, and there is nothing to sign up for. Every conversion is free, there is no paid tier, and the limits are the same for everyone.

Will the quality change when converting to WAV?

Converting to WAV is lossless, but it cannot restore detail that the original MP4 file already discarded. The result matches the source exactly as it is.

What happens to my file afterwards?

The uploaded file is deleted as soon as the conversion completes, and the converted file is removed automatically once its retention window ends. Download links are signed and expire within minutes.
