    About FLV and MP3

    FLV: FLV is the Flash Video format that powered early YouTube. Flash is gone, so FLV files usually need converting to play today.

    MP3: MP3 is the most widely supported audio format in the world. It uses lossy compression to make music and voice files small enough to share, while keeping quality good enough for everyday listening.

    Frequently asked questions

    How do I convert FLV to MP3 on my phone?
    Open this page in your phone's browser (Safari, Chrome, Samsung Internet), tap Choose files, pick your FLV, make sure MP3 is selected and tap Convert. The MP3 file is saved to your Downloads.
    Will converting FLV to MP3 reduce quality?
    Only the sound is kept — the picture is dropped, so the MP3 file is far smaller than the FLV video.
