About this tool
Converting M4A to WAV
M4A is the Apple-native container around AAC audio — the default format of iTunes, iPhones, and voice memos on Apple devices. WAV stores audio uncompressed — every sample bit-exact, editing-grade quality, at roughly ten times the size of MP3. Decoding M4A to WAV exposes uncompressed samples for editing — the standard pre-processing step.
What to check after converting
Listen to a section you know well — the beginning, the loudest part — and compare it against the original file. The WAV output is an exact capture of the decoded source. Your original file stays untouched on your device either way.
Frequently asked questions
Will converting M4A to WAV reduce the quality?
No further loss — WAV stores the decoded audio exactly, though what earlier lossy encoding discarded stays discarded.
Is my audio file uploaded anywhere?
Small files convert entirely in your browser; larger ones finish on our servers and auto-delete within an hour. Either way, nothing is kept, shared, or used for anything else.
Why would I pick WAV over M4A?
