Free tools for M4R to MP3

- 3
FFmpeg (command line)
ffmpeg -i input.m4r -c:a libmp3lame -b:a 192k output.mp3. It's the same command as for M4A, since M4R is AAC audio in an MPEG-4 file.

Set it as a ringtone on Android
Copy the MP3 to the phone's Ringtones folder, then pick it in Settings → Sound. Menu names vary a little by phone maker.
Why convert M4R to MP3?
M4R is iPhone-only; MP3 plays everywhere. Converting M4R to MP3 frees your custom ringtones from the Apple ecosystem.
Frequently asked questions
FFmpeg command for M4R to MP3?
`ffmpeg -i input.m4r -c:a libmp3lame -b:a 192k output.mp3`. Since M4R is identical to M4A, this is the same command you'd use for M4A to MP3.
Can I just rename M4R to MP3?
No. Renaming changes only the extension; the file content is still AAC inside MPEG-4. Music players that read by file format (not extension) will fail. You need actual transcoding from AAC to MP3.
Will the ringtone sound the same after conversion?
Both M4R (AAC) and MP3 are lossy. Converting between two lossy formats compounds quality loss slightly. At 192 kbps MP3, the difference is virtually imperceptible — fine for ringtones.
