The page I need help with: https://www.ladtransport.com/transport-miedzynarodowy/ Hi @pbpiotr, the image (tloparallaxwebp_1.jpg) does not get a WEBP version, please check on media library to see does it optimized of just missing the WEBP version. Hi @stanleylitespeed Thank you for your response. This image jpg is have a webp version. Screen: https://i.ibb.co/KKPrwMY/webpthisimage.png Best regards I did many tests. I only added: and this image jpg also has not changed to the webp format On the media library, you can see the WEBP % chart is dimmed (grey-out), thats mean the main file for that does not be compressed. It might because the original image is small enough and cannot do anymore compression, or theres a server error. In your case, the tloparallaxkrajowa.png is already compressed in jpg format, so our server does not return a WEBP version. How to set all photos to be served webp format? If the image already fully compressed our server will not send back a WEBP format. Also, if the image is already compressed, serving WEBP or JPG version will not affecting the score on PageSpeed or GTMatrix, so its fine to use a JPG version. Do you have any concern that must serve WEBP version? I would like serve all media webp format for support browser, because the Google Page Speed Insight prefer webp format. You have a great plug and its a shame that this feature is missing. Maybe unless the jpg version does not affect Google? I am sorry if I am wrong. Best regards If the image already optimized, it will not affect the pagespeed score, you can check on this report, no optimize image warning is showing.
