Why convert MP3 to WAV?
MP3 is a compressed format, which means data was thrown away to make the file smaller. While an MP3 is great for listening on your phone, you should never use an MP3 if you are dropping samples into a music production session or sending vocals to a mixing engineer.
Converting an MP3 back into a WAV file puts the audio into an uncompressed format. This is required by almost all professional mastering software, CD burning tools, and high-end video editors.
How to convert your audio
Simply upload your MP3 file. Our converter will instantly decode the compressed audio and wrap it in an uncompressed 16-bit or 24-bit WAV container.
Once the processing is finished, download your new WAV file. Because this happens entirely in your web browser, it is blazing fast and you do not have to worry about strict upload file size limits.
Frequently Asked Questions
Will converting to WAV improve the audio quality?
No. Once the quality is lost by compressing it to an MP3, it is gone forever. Converting to WAV simply prevents any further quality loss when you start editing or saving the file again.
Why is the new file so much bigger?
WAV files are completely uncompressed. Even if the source was a tiny MP3, the WAV container has to map out every single sample of silence and data, resulting in a massively larger file size.
Should I choose 16-bit or 24-bit?
If you are burning a standard CD, you must use 16-bit. If you are bringing the audio into a DAW for professional mixing, 24-bit is the industry standard.
