02 / what you get
What happens to your data
Kept
- Constant and variable bitrate MP3 files of any length are supported
- Saved as M4A (AAC) at 192 kbps, which plays on iPhone, iTunes, Apple Music and almost every modern player
- Title, artist and album tags are carried over
Good to know
- Embedded cover art is not carried over. Only the sound is converted.
- Both formats compress with quality loss, so every conversion costs a little quality. Keep your MP3 original.

MP3 vs M4A
MP3
An MP3 file is the most common compressed audio format — small file size, works everywhere, though it loses some audio quality in the process. It's what you'll get from most music downloads, podcasts, and voice recordings.
Used in: Music downloads · Podcasts · Universal playback
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
