    Only the sound is kept — the picture is dropped, so the M4R file is far smaller than the WEBM video.

    About WEBM and M4R

    WEBM: WebM is Google's open video format using VP8/VP9 and Opus. It is built for the web and is what screen recorders and browsers produce.

    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 WEBM to M4R on my phone?
    Open this page in your phone's browser (Safari, Chrome, Samsung Internet), tap Choose files, pick your WEBM, 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.
    Can I convert only part of the WEBM?
    Yes. Open Advanced options → Trim and enter a start and end time.
    Will converting WEBM to M4R reduce quality?
    Only the sound is kept — the picture is dropped, so the M4R file is far smaller than the WEBM video.
    Is this WEBM to M4R converter free?
    Yes — completely free with no limits on the number of files, no watermark and no account. The site is supported by ads.
    Are my files uploaded to a server?
    No. The converter runs inside your browser using WebAssembly, so your files never leave your device. That's also why it works for private and confidential recordings.
