Why convert to WAV?
WAV is uncompressed PCM audio — the standard for professional audio editing, DAWs like GarageBand, Logic, Audacity, and Pro Tools. If you're editing voice memos or working with audio professionally, WAV is what you need.
Sample rate guide
44,100 Hz — CD quality, universal compatibility.
48,000 Hz — video/film standard, use if syncing to video.
22,050 Hz — half CD quality, smaller file, fine for voice.
16,000 Hz — voice only, smallest file, used for speech recognition.
FAQ
Will quality improve converting M4A to WAV?
No — the original M4A quality is preserved, not improved. WAV is lossless so no further quality is lost in the conversion.
Why is my WAV file so large?
WAV is uncompressed. A 1 minute stereo file at 44,100 Hz is about 10 MB — much larger than M4A.
Are my files uploaded anywhere?
No — all conversion happens locally in your browser using the Web Audio API. Nothing is sent to any server.
Does it work on iPhone?
Yes — works in Safari on iPhone and Chrome on Android.
