How to compress a MKV

  1. Choose the file

    Drop a MKV on the orange block, or pick it from your device, a link or your cloud.

  2. Compress

    It’s saved again as a MKV with lighter settings. There’s nothing to configure.

  3. Check the size

    The result shows both sizes. If the MKV didn’t get smaller, it says so, and your original stays as it was.
