Why is it limited to 40 seconds?

iPhone ringtones cannot exceed 40 seconds, so the tool enforces that limit to guarantee your file will load.

Can I add the ringtone without a computer?

Apple requires syncing ringtones through Finder or iTunes; the .m4r file is created here but must be transferred via a computer.

What is an M4R file?

M4R is Apple's ringtone format — AAC audio in an MPEG-4 container with a .m4r extension. iPhones only accept ringtones in this format, up to 40 seconds long.

How to make the ringtone

Load a song, drag the sliders to the catchiest 40 seconds or less, and export. The tool encodes AAC and writes an iTunes-compatible .m4r for you.

Getting it onto your iPhone

Connect your iPhone, open Finder (or iTunes on Windows), and drag the .m4r file onto your device under the Tones section. It then appears in Settings → Sounds.
