Why convert AIFF to M4R?
AIFF — Apple's version of WAV. Top sound quality, large files.
M4R — iPhone ringtone — same AAC-in-MP4 as M4A, with the .m4r extension iOS imports as a ringtone.
AIFF keeps the song exactly as it was recorded. M4R makes a much smaller file by leaving out parts of the sound most people can't hear. At the standard quality setting, the difference is hard to notice for most listeners on most devices.
All of this happens right inside your web browser. Your file stays on your phone or computer the whole time.
Frequently asked questions
