About converting MKV to FLV
MKV and FLV solve different problems, which is why this conversion is so common. Our converter reads the structure of your MKV file and rebuilds it as a valid FLV file rather than simply renaming it, so the result opens cleanly in the apps you already use.
MKV is a flexible open video container that can hold many audio and subtitle tracks. FLV is the Flash video format, now mostly legacy.
The converter sits in our video converters toolkit alongside MP4, MOV, AVI, MKV, WEBM, FLV, WMV, MPEG and more. Nothing is installed, nothing is stored, and the output carries no watermark.
