What happens to your data
Kept
- Both AAC and Apple Lossless (ALAC) M4A files are supported
- iPhone voice memos and iTunes / Apple Music files work
- Saved as uncompressed 16-bit WAV with the original sample rate and channels
- Title, artist and album tags are carried over
Good to know
- Copy-protected (DRM) files cannot be converted.
- WAV files are big, about 10 MB per minute for CD-quality stereo.
- A 24-bit hi-res file is reduced to 16-bit in the WAV. Choose FLAC to keep 24-bit.
- Embedded cover art is not carried over. Only the sound is converted.
- If your M4A is regular AAC, converting to a lossless format makes the file bigger without adding quality. An Apple Lossless (ALAC) M4A keeps its full quality.

M4A vs WAV
M4A
An M4A file is a compressed audio format (usually AAC inside an MP4 container) used by Apple's ecosystem — iTunes, Apple Music, and voice memos on iPhone all default to it. Slightly better quality than MP3 at the same file size.
Used in: Apple Music & iTunes · iPhone voice memos · Audiobooks
WAV
A WAV file stores audio completely uncompressed — full quality, but large file sizes. It's the standard for professional audio editing, recording, and mastering, where quality matters more than size.
Used in: Audio editing & mastering · Professional recording · Sound design
