M4A vs WAV: what’s the difference?
M4A is an audio container that most often holds AAC (lossy) or ALAC (lossless). WAV stores uncompressed PCM. Choose WAV when you need easy editing, mastering, or archiving. Expect larger files, and note that artwork or some tags may not carry over to WAV.
How to convert M4A to WAV online
Use the converter at the top of this page. Upload your M4A, we process it on our servers, then you download the WAV. Keep the original sample rate and bit depth unless you have a specific target in mind. For audio you can submit up to 20 files at a time.
Why Converter App? It’s 100% free with no signup, fast turnaround, and fair-use friendly. Large files are supported; that’s mainly relevant for video workflows, but long audio is fine. Your files are handled over HTTPS and removed automatically after processing.
Will quality change?
If your M4A uses AAC, converting to WAV won’t add detail—it just makes an uncompressed copy of the current quality. If it’s ALAC, your WAV will be fully lossless. Tip: keep the source sample rate to avoid resampling, and remember some metadata may not transfer to WAV.
