    About AVI and FLAC

    AVI: AVI is Microsoft's classic video format from the Windows 95 era. It is still used by older cameras, DVD players and Windows software.

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

    Yes. Open Advanced options → Trim and enter a start and end time.
    Is this AVI to FLAC converter free?
