Is there a way to force a one-time re-generation of image size variations?

A while back I added webp support to arthistoryproject.com, but didn't see a ton of image size improvement. Then today I read this post by the genius horst, and realized I could tweak webp quality settings in config.php. I've made some changes, and new webp renders are WAY smaller. Fantastic!

But now I'm wondering if there's a way to programmatically delete/overwrite previously rendered image variations, either site-wide or page-by-page. But of course, only once per page/image. Does that make sense? Thanks so much for any ideas!

Maybe this? https://processwire.com/modules/pageimage-remove-variations/

Oh snap! That looks like it might do it — I'll check it out and report back ?

If you just want to delete all WebP files you also could do this via the command line in your site/assets/files:

find . -name "*.webp" -type f -delete

But only if you don't have WebP files manually uploaded in your file fields, so be careful.

The module posted above is more safe I think. ?

There was also a receipe by Ryan a while ago, but I cannot find it.
