02 / what you get
What happens to your data
Kept
- Constant and variable bitrate MP3 files of any length are supported
- 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
- 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.
- Both formats compress with quality loss, so every conversion costs a little quality. Keep your MP3 original.

MP3 vs M4R
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
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
