When to convert audio to M4R

Before converting

Quality and limitations

Converting audio does not improve the quality of the original recording. The finished M4R file depends on the clarity and condition of the source file.

M4R is intended for iPhone ringtone workflows. Keep ringtone clips short and use M4A or MP3 when you need a general listening format.

Your selected file is processed on your device. For long or large files, keep the page open and avoid running too many other applications until conversion finishes.

Damaged, protected, or unusually created files may not open successfully. If conversion fails, try the original file or a more widely supported source such as MP3 or WAV.
