I've got a backup of images, but they are in webp format, I'm not sure how this works but...
are there any risks about this?
I mean, I see they are pretty small, and I don't know if they need internet conection or something to be rendered, or how they work, I want to know if they just reference to something in the web, and that is removed, if so, which would be a way to massively change webp to another "more reliable format"?
