Why Convert M4R to AMR?

M4R files are Apple's proprietary ringtone format, designed exclusively for iPhones. If you want to use your custom iPhone ringtone on an older feature phone or Android device that requires AMR format, you need to convert it first.

AMR (Adaptive Multi-Rate) is a widely supported audio format optimized for voice and ringtones. It was the standard ringtone format for many Nokia, Samsung, and other feature phones throughout the 2000s and early 2010s.

How to Convert M4R to AMR

  1. Upload your M4R file - Drag and drop or click to select your iPhone ringtone
  2. Confirm AMR output - The converter will process your ringtone file
  3. Download the AMR file - Transfer it to your target phone

The entire process takes just seconds. No software installation required.

M4R vs AMR: Technical Comparison

Understanding the differences helps you know what to expect from the conversion:

  • M4R - AAC-based audio in an MPEG-4 container, limited to 40 seconds for iPhone ringtones, higher audio quality
  • AMR - Speech-optimized codec with 8kHz sampling rate, designed for voice clarity over music

In our testing, ringtones with clear melodies and simple tones convert best. Complex music with lots of bass may lose some depth in AMR format due to its voice-optimized compression.

When to Use This Conversion

Legacy Phone Support

Older feature phones from brands like Nokia, Samsung, and LG often only accept AMR ringtones. If you have a favorite iPhone ringtone you want on a secondary phone, AMR conversion makes it possible.

Universal Sharing

When sharing ringtones with friends or family who use basic phones, AMR ensures maximum compatibility across devices.

Smaller File Sizes

AMR files are extremely compact, which can matter for phones with limited storage.

Alternative Formats to Consider

If AMR quality isn't sufficient for your needs, consider these alternatives:

  • M4R to MP3 - Better audio quality, widely supported on smartphones
  • M4R to WAV - Uncompressed quality for editing purposes

For modern Android phones, MP3 is usually the better choice. AMR is primarily useful for older devices that don't support newer formats.

Browser-Based Conversion

This converter works entirely in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android devices

No downloads, no account creation, no waiting. Just convert and transfer to your phone.

Pro Tip

For best results with AMR conversion, choose ringtones with clear, simple melodies rather than bass-heavy music. AMR's voice-optimized codec handles mid-range frequencies better than low bass tones.

Common Mistake

Using AMR for modern smartphones when MP3 would provide much better quality. AMR is only necessary for legacy feature phones that don't support newer formats.

Best For

Converting iPhone ringtones for use on older Nokia, Samsung, or LG feature phones that only accept AMR format ringtones.

Not Recommended

When you need high audio quality or when your target phone supports MP3. AMR compression sacrifices quality for small file sizes.
