How to convert MKV to OGV
- 1 Drop your MKV .mkv file onto the page, or click to browse for it.
- 2 Set the quality, or leave the default, which keeps the file small without anything showing.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the OGV, or add more files and do the whole set in one go.
Why convert MKV to OGV
- Completely patent free and open.
- Supported natively by Firefox and Chrome.
- Wikimedia Commons and other free-culture media archives.
- MKV: cannot be streamed on a web page without repackaging it first.
MKV compared with OGV
How the two formats differ on the things that decide whether a conversion is worth making.

| File extension | .mkv | .ogv |
| Compression | Lossy or lossless | Lossy |
| Typical file size | Depends on mode | Smaller |

Quality and what changes
OGV stores the same content under a different set of rules, so what matters here is compatibility rather than picture quality. Convert once from the best source you have rather than through a chain of intermediate files.
- One OGV limitation to keep in mind: quality for the file size is well behind MP4 or WebM.
Questions about MKV to OGV
Is my MKV file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your MKV is read straight from your own disk, converted on your machine and handed back as an OGV. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several MKV files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate OGV downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
