MKV to OGG Converter

What happens when you convert MKV to OGG

• OGG holds sound only, so the picture is discarded and the soundtrack is encoded as Vorbis at 192 kbps.
• If the MKV has several audio tracks, the first one is used.

How to convert MKV to OGG online

1. Press "Choose MKV files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
2. Adjust the settings if you need to: the bitrate controls quality and size. The defaults suit most people.
3. Press "Convert to OGG". The first audio or video conversion downloads the converter engine, about 32 MB, which your browser then keeps for next time.
4. Save each OGG with its download button. Close the tab and every trace of the files is gone from memory.

Why convert MKV to OGG?

MKV files usually come from films and TV rips, OBS recordings and anime releases. People convert them to OGG because OGG Vorbis is free to use and is the standard audio format of many games and game engines.

In short, MKV is good at what it was made for, and OGG is the more practical choice when the file has to play on another device or app. Chrome and Edge play many MKV files; Safari and iPhones do not, while OGG plays in Chrome, Firefox and Edge; Safari support is recent and incomplete.

How to convert MKV to OGG on Windows, Mac, iPhone and Android

On Windows

Open this page in Chrome, Edge or Firefox, drag your MKV files in from File Explorer, and press Convert. Each OGG is saved to your Downloads folder. If you prefer a desktop program, VLC can also convert MKV to OGG: choose Media, then Convert / Save.

On a Mac

Safari, Chrome and Firefox all work. Drag the MKV files from Finder onto the drop zone and the OGG files land in Downloads.

On iPhone and iPad

Open the page in Safari and tap Choose MKV files. You can pick from Photos or from the Files app. The converted OGG appears in Files, in the Downloads folder.

On Android

Open the page in Chrome, tap Choose MKV files and pick them from Files or your gallery. The OGG is saved to the Download folder, where any file manager can find it. Keep the screen on while a long video converts, because Android may pause a tab in the background.

Best settings for MKV to OGG

OGG is a lossy format, so the bitrate decides both the sound quality and the file size. Size grows in a straight line with bitrate: double the bitrate and the file doubles.

The MKV was already compressed, so pick a bitrate at least as high as the original. Going higher does not add quality back, it only makes the file bigger.

MKV vs OGG: the differences

About MKV and OGG files

What is an MKV file?

MKV can hold unlimited audio tracks, subtitle tracks and chapters in one file, which is why film rips use it. OBS offers MKV recording because a crash part way through does not corrupt the whole file.

What is an OGG file?

OGG is a free, patent-unencumbered container, and most .ogg files hold Vorbis audio. Game engines use it heavily because it costs nothing to license.

MKV to OGG not working? Common problems

• The conversion is slow. Audio and container changes take seconds, but re-encoding video runs on your own processor. Lower the resolution to 720p, close other tabs, and keep the device plugged in.
• The tab stops or reloads on a very large file. Browsers limit how much memory one tab can use, around 2 GB and less on phones. Split long recordings or convert them on a computer.
• Song titles are missing. Tags such as title and artist are copied when OGG can store them, but cover art is not carried over.

Convert MKV to OGG with ffmpeg

This converter runs ffmpeg inside your browser. If you would rather use the ffmpeg command line on your own computer, this command produces an equivalent OGG with the same kind of settings:

ffmpeg -i input.mkv -vn -c:a libvorbis -b:a 192k output.ogg

Replace input.mkv with the name of your file. For a whole folder of MKV files, run the command in a loop, or drop them all on the converter above, which processes them one after another.
