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 a raw AAC (ADTS) stream at 192 kbps
Good to know
- Copy-protected (DRM) files cannot be converted.
- A raw .aac file has no room for title, artist or album tags. Choose M4A if you want the tags kept.
- Some players show a slightly wrong length for raw AAC files and cannot jump around in them as smoothly as in M4A.
- Embedded cover art is not carried over. Only the sound is converted.
- Lossy compression permanently removes some detail. Keep your original if you want to archive the recording.

M4A vs AAC

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
AAC
An AAC file is a compressed audio format similar to MP3 but with better sound quality at the same bitrate. It's the standard for streaming audio, YouTube, and most modern devices' default recordings.
