Leverage browser caching

Have you set the caching in WebP Express settings > General > Cache-Control header ?

Ah, I see that you are on Nginx.
You will have to add rules manually to your nginx config.
Check out the “I am on Nginx” section in the faq

You will need something like this:
(this sets expiry to 365 days, you might want to start lower)

location ~* ^/wp-content/.*\.(png|jpe?g|webp)$ {
    expires 365d;
}

Unless there is some magick on the server, .htaccess files will not be working.
This also means that the redirects in the Varied Image Responses mode probably does not have any effect. You should use “CDN friendly” mode.

With regards to caching, perhaps you host supports setting this through a control panel? If you have no control what-so-ever and the host cannot help you with a simple thing as setting cache-control, consider changing host 🙂

Great, and thanks 🙂
