HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload the MP3
Drag and drop your MP3 files or select them from your device. To use a part other than the start, trim the MP3 first.
02
Convert to M4R
Keep M4R as the output and start. The first 30 seconds become an AAC ringtone.
03
Download the ringtone
Save the .m4r file, then add it to your iPhone through Finder on a Mac or iTunes on Windows.
MP3
MP3 is a lossy compressed audio format built for small files and broad playback compatibility. It works on almost every phone, browser, car stereo, media player, and editing application.
M4R
M4R is the iPhone ringtone format: AAC audio in an MPEG-4 container, the same as an .m4a file but with a different extension so iTunes, Finder and iPhone treat it as a ringtone. iPhone ringtones can be up to 40 seconds long, and text or alert tones up to 30 seconds.
FILE FORMATS
SOURCE
MPEG-1 Audio Layer III has been the universal music format since the 1990s. It compresses audio by removing sounds the ear is unlikely to hear, so a song takes a few megabytes instead of tens. ID3 tags carry the title, artist and album art, and every phone, browser, car stereo and editor plays it.
TARGET
M4R is the iPhone ringtone format: an AAC file in an MPEG-4 container with a different extension, so iOS lists it under Ringtones. Ringtones are short, and Apple caps them at 40 seconds. You add them to an iPhone through Finder, iTunes or GarageBand.

USE CASES
Practical workflows where MP3 to M4R conversion is useful.
Turn a favorite song into a ringtone
Convert the MP3 and add the .m4r to your iPhone through Finder on a Mac or iTunes on Windows.
Use a song with a strong intro
Songs that open with their hook work best, because the ringtone is always the first 30 seconds.
Make a ringtone from a trimmed chorus
Cut the chorus into its own MP3 first, then convert it. Clips of 30 seconds or less are kept whole with no fade.
Give a contact their own ringtone
Assign a distinct ringtone to a family member or your manager so you know who is calling before you look.
Turn a voice recording into a ringtone
A child saying hello or a short spoken message makes a personal ringtone. Mono recordings stay mono.
Make a text or alert tone
Short clips also work as text and alert tones, which iPhone limits to 30 seconds.
Use a team jingle on work iPhones
Turn a short company jingle or podcast intro into a ringtone for the team.
Use a short sound effect
A sound effect MP3 under 30 seconds is kept whole in the ringtone, with no fade and no cut.
Bring Android ringtones to a new iPhone
Moving from Android? Ringtones you used as MP3 files can be converted to .m4r for the iPhone.
Show the song name as the ringtone name
The MP3's title tag is kept, and iOS shows the title as the ringtone's name.

TROUBLESHOOTING
Most problems come from adding it to the iPhone.

03
Songs longer than 30 seconds get a fade at the end.
04

05
