    Frequently asked questions

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

    Yes — completely free with no limits on the number of files, no watermark and no account. The site is supported by ads.
