Frequently Asked Questions
Is MP4 or WAV better quality?
WAV is a lossless format while MP4 is lossy. Converting to WAV preserves the audio exactly as decoded, but cannot recover quality lost during the original MP4 compression.
Will I lose quality converting MP4 to WAV?
No — this conversion is lossless. The audio data in your MP4 file is preserved exactly in the WAV output.
How long does conversion take?
Seconds for most files. Conversion runs entirely on your device — no upload wait, no server queue. Longer files (over 30 minutes) may take slightly longer.
