> Hi > I don´t think IPRO makes any image conversion, it recopress the image but don´t change the image type because IPRO don´t change the url. > If you enable convert_png_to_jpeg and convert_jpeg_to_webp then the png image get converted to lossily-encoded WebP That's not entirely true; it might be a little confusing, but the module may transform formats even though the extension mentioned in the url does not change. It will change the content-type when it does this though. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
