        Wait till you find out what’s inside when you change Office files from .***x to .zip

      Why does this even work though? WEBP and PNG are very different file formats yet for some reason this has always worked for me as well. Is windows automatically converting the files? I haven’t checked if changing the file extension changes the file size.

        WebP is an extended container around the RIFF file format, and contains the RIFF header info. So any container that is built off RIFF, or supports RIFF, can at least interpret the container data that is RIFF compatible and will lose anything that has been extended upon.
