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