“I love Justin Timberlake's music and would like to set old classics like CAN'T STOP THE FEELING! and Mirrors as ringtones on my iPhone. I recorded his songs from YouTube in .mp3 format and shortened them using an audio cutter, but I still can't set any of the snippets as ringtones.”

iPhone ringtones can only be in .m4r format, while the most common audio format is .mp3, making it difficult to change and create personalized ringtones.

Done with applying iPhone preset ringtones or intermittently buying M4R ringtones from the iTunes Store? Convert songs from MP3 to M4R format! Here's what I've recently tested, and confirmed works on desktop.

Pick a solution to convert MP3 to M4R on your computer:

Solution Who it's for
#1 Use iTunes (or Music) For people who want to convert individual files securely and free of charge.
#2 Use Cisdem VC Ideal for all users okay with paying: support batch, any media file (incl. music, YouTube, DVD, and Blu-ray) conversion, simple, safe.
#3 Use online converter For those who want it to be free but easier than iTunes. And willing to take the risk of the internet.

 

What is the maximum length of a ringtone on iPhone?

This is what you need to know before converting MP3 to M4R. iPhone has a restriction on the length of ringtones, and musical excerpts can't be longer than 30 seconds, so make sure you cut the audio before exporting to M4R.

Some sources say that the iPhone ringtones can last up to 40 seconds. I'm a tad puzzled, at least on my iPhone 15 Pro Max it's 30 seconds.

Ringtones usually only capture the chorus, and 30 seconds is more than enough. If you want to extend the ring time on your iPhone, there's a way to do that, too.

 

Solution #1 Convert MP3 to M4R Using iTunes or Apple Music, Built-in Audio Cutter Supported

iTunes can't directly convert MP3 to M4R, but it has the ability to convert MP3 to M4A which is also encoded in AAC. M4R is closely resembling the M4A. Simply rename .m4a to .m4r, and you are able to transfer the file to your iPhone for use as a ringtone. Comply with the instructions to change MP3 file to M4R for free in iTunes.

  1. Install and open iTunes on your computer.
    Without downloading, Mojave and earlier users can open iTunes pre-installed on Mac outright, and Catalina+ users can employ its successor - the Music app.
    On Windows 10 or 11, you will need to download the iTunes .exe file from the Microsoft Store and install it.
  2. Under the "Library" tab on the left, select "Songs", and add MP3s you want to turn into ringtones.
  3. Right-click the song, go to "Song Info" or “Get Info” > “Options”.open song info
  4. Set start/stop times to cut the song accurately. Click on “OK”.cut mp3 in itunes
  5. Hold down the "Shift" key and select all imported MP3 music.
  6. Head to “File” > “Convert” > “Create AAC version”, and your audio files will be converted into M4A format one by one.convert mp3 to m4a in itunes
  7. Rename M4A files to M4R.

 

Useful tips for converting MP3 to M4R in iTunes:

  • iTunes not only generates M4A files, but also duplicates of the original MP3 files. To get rid of them, Go to preferences to see if the "Copy files to Music Media folder when adding to library" option is unchecked.
  • If you don't see the option to "Create AAC version", Move to "Preferences" > “General” or “Files” tab, click “Import settings”, and select the “AAC Encoder” option there.import using aac encoder
  • To quickly locate the converted files, right-click them in iTunes, choose “Show in Windows Explorer” or “Show in Finder”.
  • On a Mac, you can change the suffix of all .m4a files to .m4r once and for all. Just select all converted M4As, right-click on them and pick "Rename". Fill in m4a in the “Find” field and m4r in the “Replace With” field and click “Rename”.change m4a to m4r

Where it falls short:

  • Can only be renamed from a M4A file, not a true M4R
  • iTunes for Windows cannot batch rename
  • The Windows version is confusing to manage and converted files may appear in different folders

Solution #3 Convert MP3 to M4R Online Free, No Program Needed

Another alternative to iTunes is a free online MP3 to M4R converter, there are a few of these websites and I tested the top 5 most popular ones.

Convertio.co: Max 100MB upload; 2 concurrent conversions; 10 conversion minutes per day

Zamzar.com: Input cannot exceed 50MB; can only change a total of two MP3 files to M4R for free

MP3.to: Convert files up to 2 GB for free; slower processing of larger files (e.g. 50MB audio files); merely allow adding one file at a time

Online-convert.com: Failed to convert large files; support simultaneous processing of 3 audios

Audio.online-convert.com: Maximum upload file size 200 MB; handle up to one file at a time

Online MP3 to M4R converters can be used without installing software, but most of them have slow conversion speeds, may leak private information, and cannot cut output M4R files. In addition, they have a limitation on the size of the uploaded files. Luckily, audio files are usually not large enough to be bothersome.

Of the 5 sites tested, Convertio.co narrowly won, so let's find out how to convert MP3 to M4R online via Convertio.co.

  1. Visit https://convertio.co/mp3-m4r/ in your web browser.open online mp3 to m4r converter

Q&As

1. Can Audacity convert MP3 to M4R?

Like iTunes, it’s only able to convert MP3 to M4A, and then rename the file, there is no direct M4R output option. It's worth mentioning that you can install the FFmpeg library for Audacity to convert M4R to MP3.

2. Is it possible to change MP3 to M4R with GarageBand?

No direct audio conversion is possible. But if your purpose is to set MP3 as an iPhone ringtone, iOS devices permit you to share MP3 from GarageBand to the iPhone ringtone library.

Add the MP3 file into GarageBand and edit it. In “GarageBand Recents”, long-press the MP3, tap “Share” > “Ringtone”, and your MP3 will be automatically shortened to 30 seconds, tap "Continue". Name the ringtone and export. For further details, see https://www.youtube.com/watch?v=Il81mZ-WXbA.

3. How to transfer M4R ringtones from computer to iPhone?

If your iTunes is prior to 12.7, you can transfer ringtones directly through the Tones library. For later versions, refer to https://discussions.apple.com/docs/DOC-12051 to know how to add ringtones to iPhone from computer for free, or purchase Mobikin iOS Transfer, a tool specifically designed for iOS data transfer and management.
