    About MKV and MP3

    MKV: MKV is a flexible open container that can hold unlimited video, audio and subtitle tracks. It is popular for movies and anime but isn't supported by iPhone or most TVs out of the box.

    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 MKV to MP3 on my phone?
    Open this page in your phone's browser (Safari, Chrome, Samsung Internet), tap Choose files, pick your MKV, make sure MP3 is selected and tap Convert. The MP3 file is saved to your Downloads.
    Will converting MKV to MP3 reduce quality?
    Only the sound is kept — the picture is dropped, so the MP3 file is far smaller than the MKV video.
    Can I convert only part of the MKV?
    Yes. Open Advanced options → Trim and enter a start and end time.
    Is this MKV to MP3 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.
