Frequently Asked Questions
Is M4A or WAV better quality?
WAV is a lossless format while M4A is lossy. Converting to WAV preserves the audio exactly as decoded, but cannot recover quality lost during the original M4A compression.
Will I lose quality converting M4A to WAV?
No — this conversion is lossless. The audio data in your M4A 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.
