About MKV and OGG
Matroska (MKV) .mkv
Matroska: an open container that will hold almost any combination of video, audio, subtitle and chapter tracks in one file.
Good for
- Unlimited tracks — multiple languages, subtitles, chapters
- Codec-agnostic, so it holds nearly anything
- Open, well documented, and resilient to damage
Trade-offs
- Browsers will not play it natively
- Many TVs and phones refuse it — the usual reason to convert
- Being a container, contents vary wildly file to file
video/x-matroska
OGG Vorbis .ogg
An open container, normally holding Vorbis audio. Created specifically to avoid the patent licensing that surrounded MP3.
Good for
- Open and royalty-free
- Better quality than MP3 at the same bitrate
- Standard in games and open-source software
Trade-offs
- Lossy
- Patchy support on consumer hardware
- Largely superseded by Opus for new work

What changes when you convert MKV to OGG
Only the sound is kept
This takes the audio track out of the MKV and writes it as OGG. The picture is discarded entirely, and no conversion back will return it — keep the MKV if you still need the video.
This is a re-encode, not a repackage
Some tools can move a stream into a different container untouched when the codecs happen to line up. We do not — every job here is decoded and encoded again, so the conversion takes time in proportion to the length of the file and costs a small amount of quality even where a repackage would have been possible. In exchange the output is predictable: it plays everywhere, rather than inheriting whatever the source happened to contain.
What your OGG will contain
The output is Vorbis — at 192 kbps by default. Vorbis is royalty-free and holds up slightly better than MP3 at the same bitrate, though Opus has largely superseded it for anything new — choose OGG when something specifically expects it.

MP4, MOV and MKV are not really video formats
The extension on a video file tells you far less about it than most people assume. Understanding the difference between a container and a codec explains almost every confusing thing about video conversion.

What 192 kbps actually means, and when you need more
Bitrate is the single dial that decides how big an audio file is and how good it sounds. Here is what the numbers mean, why they are not comparable between codecs, and where the real thresholds sit.
