MKV, made compatible

MKV (Matroska) can hold almost anything — several audio tracks, subtitles, chapters — which makes it popular for screen recordings and archives. The downside is compatibility: plenty of devices and apps refuse to open it. Converting to MP4 gives you a file that works on phones, TVs, editors and websites.

Fast for OBS recordings

Screen recorders such as OBS usually write H.264 video into MKV. In that case Klipova only moves the video into an MP4 container, so the conversion is lossless and takes seconds. Videos in VP9, AV1, HEVC or other codecs are re-encoded to H.264.

Good to know

  • The main video and the first audio track are kept.
  • Embedded subtitles and additional audio languages are dropped.
  • Choose a lower resolution if you need a smaller file for sharing.

MKV to MP4 questions

Why convert MKV to MP4?

MKV is a flexible container popular with screen recorders like OBS, but many phones, TVs, editors and websites don't accept it. MP4 is supported almost everywhere.

Is the conversion lossless?

If the MKV holds H.264 video with AAC audio and you keep the original resolution, the streams are copied into MP4 without re-encoding — no quality loss, done in seconds. Other codecs are re-encoded.

What happens to subtitles and extra audio tracks?

The MP4 keeps the main video and the first audio track. Embedded subtitles and extra audio languages are not carried over.

I recorded with OBS. Will it work?

Yes. OBS recordings in MKV are usually H.264, so they convert to MP4 almost instantly.

Is there a size limit?

Files up to 500 MB and 3 hours long can be converted.
