    About WEBM and ALAC

    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.

    ALAC: ALAC is Apple's lossless format. It compresses audio to roughly half the size of WAV with zero quality loss and plays natively in Apple Music, iTunes and on every iPhone. It is saved with the .m4a extension.

    Frequently asked questions

    How do I convert WEBM to ALAC on my phone?
    Open this page in your phone's browser (Safari, Chrome, Samsung Internet), tap Choose files, pick your WEBM, make sure ALAC is selected and tap Convert. The ALAC file is saved to your Downloads.
    Will converting WEBM to ALAC reduce quality?
    Only the sound is kept — the picture is dropped, so the ALAC file is far smaller than the WEBM video.
    Can I convert only part of the WEBM?
    Yes. Open Advanced options → Trim and enter a start and end time.
    Is this WEBM to ALAC 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.
