    The picture is left out

    The MP3 is the soundtrack. A WebM that should stay a video uses the WebM to MP4 converter.

    The file needs an audio track

    A silent WebM has nothing to save as an MP3.

    Use a file you already have

    Drop a .webm file from your device. A web address is not fetched.
