Free M4R Converter

An M4R converter transforms audio and video files into the M4R format recognized by iPhone for ringtones. Even if a file plays perfectly on your device, iOS may not list it as a ringtone until it’s packaged in the M4R container. This converter solves that compatibility issue instantly.

iOS identifies ringtones based on the file container and extension, not just the audio content.

Even AAC audio inside MP3, M4A, or MP4 needs to be converted to M4R to appear as a ringtone option. Using this converter ensures your audio files are properly recognized by iPhone.

All conversions happen directly in your browser. Your files never leave your device, keeping private recordings, voice messages, and licensed music secure.
