About AVI to MKV
If you are organizing a media library, MKV gives you a flexible container that can hold multiple audio tracks, subtitles and chapters. AVI to MKV repackages your older AVI clip into Matroska so it fits neatly into a Plex, Kodi or home theater setup.
Upload your AVI and download the MKV in moments. The conversion runs in your browser with no signup, no watermark and nothing to install. Codaiman keeps it free and privacy-first, so you can move legacy footage into MKV for your media server without a desktop tool or an account-locked upload service.

FAQ
What's the benefit of MKV over AVI?
MKV is a modern, flexible container that can bundle multiple audio tracks, subtitles and chapters, which older AVI does not handle as well.
Does converting to MKV lose quality?
MKV is a container, so rewrapping your AVI into it keeps the video close to the original with no meaningful loss.
Will all my devices play MKV?
Most media players and home theater devices do, but some phones and older players don't. MP4 is safer for broad sharing.
Can I use AVI to MKV on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
