    About WEBM and FLAC

    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.

    FLAC: FLAC is an open lossless format that shrinks audio to 50–60% of WAV size without losing any quality. It is the favourite format of audiophiles and hi-res music stores.

    Frequently asked questions

    How do I convert WEBM to FLAC on my phone?
    Open this page in your phone's browser (Safari, Chrome, Samsung Internet), tap Choose files, pick your WEBM, make sure FLAC is selected and tap Convert. The FLAC file is saved to your Downloads.
    Will converting WEBM to FLAC reduce quality?
    Only the sound is kept — the picture is dropped, so the FLAC file is far smaller than the WEBM video.
