What happens when you convert M4A to WAV
| Compression | Lossy → Lossless |
|---|---|
| Size per minute | M4A ≈ 1.4 MB → WAV ≈ 10.6 MB |
| Quality | No further loss, but the WAV cannot restore what M4A compression removed |
| Tags | Title, artist and album tags are copied when the target format supports them |
| Opens in | every computer and audio editor; too large for most messaging apps |
Sizes are typical values; your files will vary with content and settings.
M4A MPEG-4 Audio
M4A is an MPEG-4 container holding AAC audio. iPhone voice memos, iTunes purchases and many recorders save M4A, and it sounds better than MP3 at the same bitrate.

Frequently asked questions
Will the WAV lose quality?
WAV is lossless, so the conversion keeps every pixel or sample that is in your M4A file. It cannot bring back detail that M4A compression already removed, and the WAV file will usually be larger.
Will the WAV be smaller than the M4A?
No, usually larger: a minute of audio takes about 1.4 MB as M4A and about 10.6 MB as WAV. WAV is lossless, so its size depends on the audio rather than a bitrate setting.
