About the MOV to MKV

Have a MOV file from your iPhone or Final Cut Pro that you want to drop into Plex, Kodi, or Jellyfin? Handytool converts MOV to MKV directly in your browser — no upload, no account, no server delay.

MOV to MKV features

  • 01

    Built for media libraries

    MKV is the format Plex, Kodi, Jellyfin, and most NAS-based media servers expect. Convert your MOV to MKV to drop it straight into your library with full metadata support.

  • 02

    Quality slider for fine control

    Use the 1–100 slider to balance file size against visual fidelity. A setting of 75–85 produces results indistinguishable from the source on most screens.

    Powered by FFmpeg compiled to WebAssembly, conversion happens locally. Your video never touches a server and nothing is logged.

MOV to MKV FAQ

How do I convert MOV to MKV?
Drop your MOV file onto the upload area (or click Choose file), adjust the quality slider if needed, then click Convert. Download the MKV file when conversion is complete.
Why convert MOV to MKV?
MKV is preferred for media servers like Plex, Kodi, and Jellyfin because it supports unlimited audio tracks, chapters, and embedded subtitles. It's also the de facto standard for high-quality video archives on NAS systems.
What plays MKV files?
VLC, MPV, Plex, Kodi, Jellyfin, PotPlayer, and most modern media players. Default Windows/macOS players don't open MKV out of the box — install VLC for universal playback.
Will I lose quality converting MOV to MKV?
Some, since the file is re-encoded. At a quality setting of 80 or above, the difference is barely perceptible. Push higher (95–100) for maximum fidelity.
Is my video uploaded to a server?
No. The converter runs entirely inside your browser using FFmpeg WebAssembly. Your video files never leave your device and nothing is stored or logged.
