About converting FLV to MP4
FLV and MP4 solve different problems, which is why this conversion is so common. Our converter reads the structure of your FLV file and rebuilds it as a valid MP4 file rather than simply renaming it, so the result opens cleanly in the apps you already use.
FLV is the Flash video format, now mostly legacy. MP4 is the most widely supported video format.
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.
