What to expect

  • M4R is an AAC audio file for iPhone ringtones; the video track is removed.
  • When the MP4 audio is AAC it can be kept without re-encoding, so no quality is lost.
  • Ringtones are usually trimmed to a short segment rather than the full clip.

Frequently asked questions

Does the ringtone lose quality compared to the MP4?
M4R is essentially an AAC audio file renamed for ringtones, so when the MP4's AAC audio is copied the sound quality is unchanged. Any quality difference comes from trimming or re-encoding, not the format itself.
Why convert an MP4 to M4R?
M4R is Apple's iPhone ringtone format, so the conversion turns a clip's audio into a tone you can assign on an iPhone. Ringtones are also usually trimmed to a short segment.
Where is an M4R file used?
M4R is used by iPhones as a custom ringtone; it is added through the device's music/sync tools. It is not a general playback format for other devices.
What gets dropped in the conversion?
The video is discarded and only audio remains. Ringtones are typically short, so most of a long clip is cut down to a brief section.
