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 an iPhone ringtone (AAC in an iTunes-style MP4) at 192 kbps
- The first 30 seconds are kept, safely under the 40-second limit of iOS ringtones
- Title, artist and album tags are carried over
Good to know
- Copy-protected (DRM) files cannot be converted.
- The ringtone always starts at the beginning of the file. To use another part of the song, trim the audio first.
- To install it, add the .m4r to your iPhone in Finder (Mac) or the Apple Devices app / iTunes (Windows), then pick it in Settings > Sounds & Haptics.
- 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.

Used in: Apple Music & iTunes · iPhone voice memos · Audiobooks
M4R
An M4R file is an iPhone ringtone: AAC audio in an Apple MP4 container, renamed to .m4r. iPhones only accept ringtones shorter than 40 seconds.
Used in: iPhone ringtones
