Convert MKV to AVI
Your MKV goes in and an AVI comes out. AVI is the usual choice for legacy video archives and camcorder tapes captured to disk. Your file never leaves your computer.

How to convert MKV to AVI
- 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 AVI, or add more files and do the whole set in one go.
Why convert MKV to AVI
- Simple, well documented structure that almost every tool can read.
- Will hold almost anything, including uncompressed capture footage.
- Files inherited from the DivX and XviD era.
- MKV: large multi-track files are unwieldy to share.
MKV compared with AVI
How the two formats differ on the things that decide whether a conversion is worth making.
| Property | MKV | AVI |
|---|---|---|
| File extension | .mkv | .avi |
| Introduced | 2002 | 1992 |
| Developed by | Matroska community | Microsoft |
| Standard | Open | Proprietary |
Quality and what changes
AVI 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 AVI limitation to keep in mind: poor support for modern video, subtitles and variable frame rates.
Questions about MKV to AVI
Can I open an AVI in a browser?
No. No mainstream browser renders AVI natively, so it will download rather than display. That is fine when the file is heading into desktop software or an archive, and a problem if it is going on a web page.
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 AVI. 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 AVI 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.
