Missing Images | WordPress.org

I’ve used the free version of this plug in for years. I am currently on a trial of the paid version because I was considering upgrading. I used the Easy I/O. Now I have a bunch of missing images. What I can discern is that a bunch of my images were converted to webp, but the links on my blog pages are still the .jpg file links. I started this blog in 2009, needless to say I’m not trying to do this manually post by post but I can’t figure out any other options. Any help/information on how to fix this would be appreciated.
