Most free converters add watermarks or throttle quality. AudioUtils does neither. You get the same output quality whether free or paid.
Free users get 5 conversions per month with a 10-second preview output. The conversion engine is identical to Pro — same speed, same quality, same privacy. Upgrade for full-length output.
Your files stay on your machine. Nothing is uploaded. MP4 is lossy. Converting to WAV won't restore lost data, but gives you an uncompressed container for editing workflows.
Frequently Asked Questions
Why extract to WAV instead of MP3 from MP4?
WAV is uncompressed, so there's no additional quality loss during conversion. Choose WAV when you plan to edit the audio. Choose MP3 when you just need a small file for listening.
How much larger is WAV than the audio in my MP4?
Roughly 5-10x larger. The audio track in an MP4 is typically compressed with AAC. Extracting to WAV gives you an uncompressed version that's much bigger but ready for editing.
Can I extract just a portion of the audio?
This tool extracts the full audio track. To trim it, convert first, then use any audio editor to cut the WAV to the section you need.
