How to convert AVI to MKV

  1. Upload your AVI file above.

  5. Start the conversion and download the finished file when it is ready.
Before you convert

AVI is usually less efficient and less web-friendly than modern MP4 or WebM workflows. Some phones, TVs and editing apps have less consistent MKV support than MP4.

Changing a container or codec cannot recreate quality already missing from the source, so keep an important original when possible.
