Why convert MP4 to WAV?
MP4 is what phones, cameras, screen recorders and most video sites produce. Editing software sometimes prefers intra-frame formats like ProRes for heavy editing. Choose WAV to edit the audio or upload it to a service that requires uncompressed audio.
Audio extraction options
Only the audio track of the MP4 is processed, so this is much faster than a video conversion. Choose the bitrate or quality, optionally trim to a start and end time, and download the WAV.
Frequently asked questions
Will the WAV lose quality?
WAV is lossless, so the conversion keeps every pixel or sample that is in your MP4 file. It cannot bring back detail that MP4 compression already removed, and the WAV file will usually be larger.
How big will the WAV file be?
About 10.6 MB per minute of audio, because WAV is lossless, so a 10-minute MP4 gives roughly 106 MB. The size of the video track does not matter, because only the sound is kept.
