M4R iPhone Ringtone Facts Explained

What is M4R

M4R is a propriety format created for iPhone ringtones by Apple. It is highly compressed but retains the best quality. Once you purchase a song in M4R format from iTunes, you'll see it transferred to your iPhone via auto-sync, and then you can customize it to the ringtone. If the M4R file is not copy-protected, it can be played in most media players.

M4R vs MP3

M4R (AAC) and MP3 (MP3) are both lossy audio formats but encoded in different ways. AAC (Advanced Audio Coding) is the default codec for audio files with all iOS devices. And it generally maintains better sound quality than MP3 at the same bitrate.

Hence, only a tool that keeps the high quality of M4R after the conversion can be nominated as the best MP3 to M4R converter. And VideoProc Converter AI is definitely the best one that performs excellently in the whole process with a lossless output. Download and use VideoProc Converter AI to make a ringtone from your favorite MP3 music now!
