Convert WebM to MP4
WebM is the open, browser-native format screen recorders and web tools default to; MP4 is what phones, editors and most non-browser software expect.
When you'd use this
Taking a screen recording exported as WebM (common from browser-based recorders) and getting it into a video editor or onto a device that doesn't support WebM.
Worth knowing
WebM (VP8/VP9) and MP4 (H.264) use different codecs, so this is a real re-encode, not a repackage — very long recordings will take noticeably longer to convert.
