3 years ago - Verify using plugins like https://wordpress.org/plugins/regenerate-thumbnails/ correctly creates WebP images when "WebP as default" is enabled
- Explore approaches to determine when a post is loaded if the sub sizes are already WebP, and if not, recreate them as WebP for subsequent load. This would let us "back convert" old image sub sizes to WebP only for posts that are still used (and not necessarily every image).
