Frequently asked questions

What is the difference between M4A and M4R?

Both are AAC audio in an MP4 container. M4R only has a different extension, and the iPhone accepts it as a ringtone only if it is no longer than 40 seconds, so the first 40 seconds are taken unless you set a fragment.

Is converting M4A to M4R free?

Yes. Conversion is free, with no sign-up and no watermarks.

Are my M4A files uploaded anywhere?

No. The conversion runs in your browser, so your files never leave your device.

Will the quality change when converting to M4R?

Quality depends on the target format and the settings you choose; lossy formats let you adjust the quality level.
