Need to Edit iPhone Ringtones?

M4R files are Apple's proprietary ringtone format. They work great on iPhones but are limited to 40 seconds and compressed with AAC. When you need to edit these audio clips or use them in professional audio software, AIFF is the better choice.

AIFF (Audio Interchange File Format) provides uncompressed, lossless audio that audio editors and DAWs handle perfectly. Converting your M4R files to AIFF preserves every detail for further editing.

How to Convert M4R to AIFF

  1. Upload your M4R file - Drag and drop your iPhone ringtone or click to browse
  2. Select AIFF as output - Choose AIFF for uncompressed audio quality
  3. Download your file - Get your lossless AIFF audio instantly

The entire process takes seconds. No software installation or account creation required.

M4R vs AIFF: Key Differences

Understanding when to use each format helps you make the right choice:

  • M4R - Compressed AAC audio, limited to 40 seconds, iPhone-specific ringtone format
  • AIFF - Uncompressed PCM audio, no length restrictions, universal DAW compatibility

In our testing, AIFF files are typically 5-10x larger than M4R but provide pristine audio quality for editing. If you need a more compressed format for general playback, consider M4R to MP3 instead.

Common Use Cases

Audio Editing Projects

Opening M4R files directly in audio editors can cause compatibility issues. Converting to AIFF first ensures smooth importing into GarageBand, Logic Pro, Audacity, or Adobe Audition.

Ringtone Modification

Want to extend a ringtone beyond 40 seconds or combine multiple clips? Convert to AIFF, edit freely, then export to your desired format.

Cross-Platform Audio

AIFF works on both Mac and Windows professional audio applications. For simpler needs, M4R to WAV offers similar uncompressed quality with broader software support.

Quality Preservation

When converting M4R to AIFF, the original audio quality is fully preserved. Since M4R uses AAC compression, the AIFF output maintains that same quality level in an uncompressed container. You will not gain resolution you did not have, but you will not lose any either.

This makes AIFF ideal as an intermediate format for editing before final export.

Works in Any Browser

Our converter runs entirely in your browser:

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

Your files stay on your device throughout the conversion process.

Pro Tip

AIFF supports metadata chunks that survive most editing operations. If you need to preserve ringtone information through your editing workflow, AIFF handles this better than WAV.

Common Mistake

Expecting higher quality from the conversion. AIFF is lossless but cannot restore detail already lost in the original M4R's AAC compression. It simply prevents further degradation.

Best For

Audio professionals who need to edit iPhone ringtones in DAWs like Logic Pro, Pro Tools, or Audacity without format compatibility issues.

Not Recommended

Simple playback on various devices. AIFF files are large and not universally supported by media players. Use MP3 or M4A for general listening.
