Free online MKV→AVI converter. Fast, private, no sign-up.
If something is asking you for a AVI file and all you have is a MKV, this page is the fix. Drop in your MKV file (a .mkv) and download a ready-to-use AVI file (a .avi) — no software to install, no account to create, and no watermark on the output.
MKV (Matroska) is a flexible open container that can hold almost any codec plus multiple audio tracks and subtitles, popular for archiving.
AVI is a long-lived Microsoft container — widely readable, but its older codecs are far less efficient than modern formats, so files tend to be large.
You'll reach for a MKV to AVI conversion whenever the other end expects AVI specifically — uploading somewhere, importing into software, or sharing with someone whose device prefers it. The conversion runs through ffmpeg, the industry-standard media engine, re-encoding the streams with sensible high-quality defaults so the result plays cleanly on your target device.
You might be optimising images for a faster-loading page, exporting for a specific app or marketplace, or just making sure a colleague on a different device can open what you send.
Privacy is the default here. Your MKV file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.

Conversions run on our servers and support large files comfortably; very large media is processed in a streaming pipeline.
