Why Convert M4R to AAC?

M4R files are iPhone ringtones - audio files limited to 40 seconds that only work in specific contexts on Apple devices. If you have an M4R file you want to use as regular audio, converting to AAC removes those restrictions while keeping the same audio codec.

The conversion is essentially a container change. M4R and AAC both use the same underlying audio compression, so the quality stays identical. You're simply removing the ringtone wrapper to get a standard audio file.

How to Convert M4R to AAC

  1. Upload your M4R file - Drag and drop or click to select your ringtone
  2. Select AAC as output - The converter handles the format change automatically
  3. Download your audio - Get a standard AAC file ready for any player

The process takes just seconds. No software installation, no account creation required.

M4R vs AAC: Technical Differences

Both formats use AAC audio compression - the difference is in the container and intended use:

  • M4R - Apple's ringtone format. Maximum 40 seconds. Only recognized by iOS for ringtones
  • AAC - Standard audio format. No length limit. Plays on virtually all devices and players

In our testing, converted files maintain identical audio quality since no re-encoding of the audio stream is needed. The file simply changes its container format.

When This Conversion Makes Sense

Repurposing Ringtone Audio

You created or purchased a ringtone and now want to use that audio clip as a notification sound, alarm, or in a project. AAC works as a universal audio format for these purposes.

Playing on Non-Apple Devices

Android phones, Windows PCs, and many media players don't recognize M4R files. Converting to AAC makes the audio accessible on any device.

Editing in Audio Software

Most audio editors import AAC files without issues. M4R sometimes requires extra steps or plugins. Converting first simplifies your workflow.

Alternative Conversions

Depending on your needs, other formats might work better:

  • M4R to MP3 - Maximum compatibility with all devices and players
  • M4R to M4A - Apple's standard audio format, maintains AAC codec
  • M4R to WAV - Uncompressed audio for editing purposes

AAC offers the best balance when you want to keep the original audio quality in a compact file that plays widely.

Works on Any Device

Our converter runs entirely in your browser:

  • Windows, Mac, Linux, Chromebook

Pro Tip

Since M4R and AAC share the same audio codec, the conversion is lossless - you're essentially just changing the file wrapper. This makes M4R to AAC one of the cleanest conversions possible.

Common Mistake

Trying to rename .m4r to .aac and expecting it to work. While the audio codec is the same, the container format differs and proper conversion is needed for players to recognize the file.

Best For

When you have ringtone audio you want to use as regular audio files on non-Apple devices or in audio editing software without quality loss.

Not Recommended

If you need maximum compatibility with older devices, convert to MP3 instead. AAC support, while widespread, isn't quite as universal as MP3.

Frequently Asked Questions

M4R is Apple's ringtone format for iPhones. It uses AAC audio compression but is limited to 40 seconds and has a specific file extension that iOS recognizes for ringtone purposes.

Yes. You can upload multiple M4R files and convert them all to AAC in a single batch. No need to process them one at a time.

Yes, the duration stays the same. Converting to AAC doesn't change the audio length - it just removes the ringtone-specific container so the file plays as regular audio.
