There is this:

lib/upload_creator.rb

7c3241188


      
          def convert_png_to_jpeg?
            return false unless @image_info.type == :png
            return true  if @opts[:pasted]
            return false if SiteSetting.png_to_jpg_quality == 100
            pixels > MIN_PIXELS_TO_CONVERT_TO_JPEG
          end
          
          MIN_CONVERT_TO_JPEG_BYTES_SAVED = 75_000
          MIN_CONVERT_TO_JPEG_SAVING_RATIO = 0.70
          
          def convert_to_jpeg!
            return if filesize < MIN_CONVERT_TO_JPEG_BYTES_SAVED
          
            jpeg_tempfile = Tempfile.new(["image", ".jpg"])
          
            from = @file.path
            to = jpeg_tempfile.path
          
            OptimizedImage.ensure_safe_paths!(from, to)
          
            from = OptimizedImage.prepend_decoder!(from, nil, filename: "image.#{@image_info.type}")

And there are some accompanying specs at upload_creator_spec.rb.
