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. Both MP4 and M4A are lossy formats. Each re-encode can degrade quality slightly. Convert once and keep the result.
Frequently Asked Questions
Is M4A better than MP3 for MP4 audio extraction?
Yes. MP4 files typically contain AAC audio. Extracting to M4A preserves the original AAC stream without re-encoding. Converting to MP3 would require re-encoding and introduce quality loss.
What happens to the video track?
Discarded entirely. Only the audio track is extracted and wrapped in an M4A container.
Will metadata transfer?
Basic metadata (title, artist, album) transfers when present in the source MP4.
