To manually convert images using cwebp:

cwebp -m 6 -mt -o "$file.webp" -- "$file"

To make nginx serve .webp files if the browser sends an accept header:

http {
    map $http_accept $webp_suffix {
        "~*webp"  ".webp";
    }

    server {
        location ~ \.(png|jpe?g)$ {
            try_files $uri$webp_suffix $uri =404;
            expires 1y;
        }
    }
}
