    M4R uses lossy compression, which makes the file much smaller than AIFF. Choose High quality and the difference is inaudible for most listeners.

    About AIFF and M4R

    AIFF: AIFF is Apple's uncompressed audio format — the Mac equivalent of WAV. It is used in GarageBand, Logic Pro and professional audio workflows.

    M4R: M4R is the iPhone ringtone format. It is an AAC audio file (the same as M4A) with a different extension, and iOS only accepts ringtones up to 30–40 seconds long.

    Frequently asked questions

    How do I convert AIFF to M4R on my phone?
    Open this page in your phone's browser (Safari, Chrome, Samsung Internet), tap Choose files, pick your AIFF, make sure M4R is selected and tap Convert. The M4R file is saved to your Downloads.
    How long can an iPhone ringtone be?
    Keep it to 30 seconds. If your file is longer, set a start time under Advanced → Trim and the next 30 seconds are used. For a visual editor, try the iPhone Ringtone Maker.
    Will converting AIFF to M4R reduce quality?
