Converting MP4 to WAV: what to know
When you need it
Audio editors, transcription services, DJ software and some broadcasting and e-learning tools ask for WAV: uncompressed audio that can be cut and processed without adding further compression losses.
What to expect
The video's soundtrack is decoded to uncompressed WAV. Files are big, roughly 10 MB per minute of stereo, and the sound is exactly as good as the audio in the video, no better.
Tip: If you only want to listen to or share the audio, MP4 to MP3 gives a file about ten times smaller.

What is MP4?
MP4 is the most widely used video container. It usually carries H.264 or H.265 video with AAC audio, and it plays on practically every phone, browser, smart TV and editing program, which makes it the safest choice for sharing and uploading.
What is WAV?
WAV stores audio as uncompressed PCM, exactly as it was recorded. That makes it the standard for recording, editing and mastering, where no quality can be lost, but a WAV file is about ten times larger than the same audio in MP3.
Tips for converting MP4 to WAV
- Only the soundtrack of your MP4 file goes into the WAV; the picture is discarded.
- WAV keeps the soundtrack without further loss, but the file is several times larger than an MP3.
- Long videos still take a while to process, and the MP4 upload itself must fit the 50MB free limit.
- Keep the original video: the audio file cannot be turned back into it.
