Why convert MOV to MKV?

MOV is Apple's native video container, widely used on Mac and iOS. MKV (Matroska) is the preferred format for media libraries, Plex and Kodi servers, and long-term archival. MKV supports multiple audio tracks, soft subtitles (SRT, ASS), and chapter markers in a single file. The conversion copies the streams directly without re-encoding, preserving full quality.

Lossless conversion

When the MOV file contains H.264 video and AAC audio (the most common case), the streams are copied into the MKV container without re-encoding. The result is zero quality loss and near-instant processing.

Frequently asked questions

Is there quality loss?

No, for the vast majority of MOV files. The streams are remuxed (repackaged) without touching the video or audio data.

Can I add subtitles to the MKV later?

MKV natively supports multiple subtitle tracks. After converting, you can add SRT or ASS subtitles using any MKV editing tool like MKVToolNix.
