@requinix thank you so much for your answer! I know a client-side solution like this one, but that would mean blocking JavaScript which will delay the page rendering. I want to serve WEBP images to Safari if supported. Maybe I could detect in PHP if the request was performed using Safari and its version to serve Webp images. Thank you anyway 🙂

I developed a server side script to check if the browser supports webp format images by checking the "image/webp" string in the accept request headers. The problem is that recent versions of Safari, even though they support Webp, they do not send the string "image/webp" in the headers. Why?? How can I check if the Safari browser supports webp??
