How to convert MP3 to WAV or WAV to MP3

Choose your audio file. Tap the box and pick a file from your phone or computer.
Choose WAV or MP3. WAV is uncompressed and good for editing. MP3 is smaller and good for sharing.
Tap Convert. Longer files take longer. Keep this page open until it finishes.
Download your file. Play it first to check it, then save it.

Use WAV when you plan to edit the audio. Use MP3 when you want a small file to upload or share.
Converting an MP3 to WAV does not bring back quality that the MP3 already lost, but it avoids losing more when you edit.
Choose 192 kbps for voice and 320 kbps for music.

What is the difference between MP3 and WAV?

WAV keeps all the audio data and makes big files. MP3 shrinks the file by removing detail most people can't hear.

Will converting MP3 to WAV improve the sound?

No. The WAV can only be as good as the MP3 it came from. It just stops further quality loss during editing.

Why is the WAV file so big?

WAV is uncompressed. About 10 MB per minute of stereo audio is normal.

Do you keep my files?

No. We don't store your files.
