There are a few ways to possibly download a .png or .jpg instead of .webp.
If you use wget or curl (the latter of which is included in recent versions of Windows) it should download the specified file. On many sites adding a parameter to the URL (even just a ? at the end) will cause them to deliver the image in the original format instead of webp.
If you set your user agent to a browser too old to accept webp that may also work depending on the site. And then there are extensions for rejecting webp, but that introduces a whole new layer of trusting the author.
All of this assumes that the image doesn’t exist only in webp format originally, but that’s rare at this point.

I want to download these locally, but they want to be .webp images.
Isn't there some sort of security flaw in that format?
