   Thanks for the responses. 
   
   Yes I am aware of how IPRO works based on the accept header, the content type and the vary header and I am quite happy with the default behaviour.
   
   According to documentation, convert_png_to_jpeg is only applicable "if they have no transparent pixels and if PageSpeed determines that they are not sensitive to compression noise". That drastically reduces the number of images that can be converted and AFAIK, it's possible to convert images with transparency to webP lossless.
   
   I wonder if there is a way to bypass this restriction and give control to the user about the quality adjustment.
