Disable webp generation for GIFs

[DrQuincy]

If you enable WebP, it creates variants for all images. However, Ryan's .htaccess code is from here:

Doesn't rewrite GIFs, I presume this is because they can be animated.

RewriteRule ^(.*?)(site/assets/files/)([0-9]+)/(.*)\.(jpe?g|png)(.*)$ /$1$2$3/$4.webp [L]

Given this, it seems inefficient to create a webp variants for GIFs. Does the core have an inbuilt way to disable this, or is it by design that this isn't offered/done automatically?

Exactly. That's the reason. 🙂

I presume, then, if you know it's not animated and you want the webp version you can use ->webp. It's probably good as it is in hindsight.
