    About MKV and WEBA

    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.

    WEBA: WEBA is an audio-only WebM file, usually containing Opus. Browsers create it when you record sound on a website.

    Frequently asked questions

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