Fallback for WebP serving using nginx So you want webp files to be named as .jpeg.webp in your htdocs. You link to images in your HTML as .jpeg. Nginx will detect if browser supports webp and automatically serve webp or jpeg (File extensions do NOT decide the type).

if ($http_accept ~* "webp") {
        set $webp "true";
}

if (-e $request_filename.webp) {
        set $webp "${webp}-local";
}

if ($webp = "true-local") {
        rewrite (.*) $1.webp last;
}
