    Hi!

    I’m using the great theme enfold!
    While uploading images there are several size-variations automatically generated i.e. myPicture-450×303.jpg, myPicture-1500×430.jpg etc.

    My original picture ist 1800×1200 with 89KB.
    The generated file 1210×423 is 90KB, the file 1500×1010 with 170KB is at least two times bigger than my original file ( with a smaller resolution ).

    I think this would give an bad performance when the smaller resolution images ( which have a bigger size ) are loaded on mobile devices..

    So where do i have to do some settings to fix this or is an special plugin necessary?

    Greetings
    Robert

    Has there ever been a resolution to this? I am very good at optimizing images, and I have my landing screen banners loading in at ~40kb at 1280×450, however when I upload they become 1024×450 and gain an extra 20kb. What gives?

    Even when uploading these, using EWW optimizer, and then WP Smush, and then EWW again, the images are still larger than when I originally export them from Photoshop. I have clients uploading images that aren’t optimized, and those are giant. Using a 3rd party plugin to resolve a theme issue doesn’t seem like a good fix.

    a bit offtopic but in the same direction:
    Wordpress itself got an image quality tool – this is in a good meaning but if the image creator knows his job excellent sometimes the 90% jpg is bad quality but more space. To avoid this from wp induced process add this to functions.php child-theme:

    add_filter( 'jpeg_quality', create_function( '', 'return 100;' ) );

    i do have now on the most sites i create this to my child-theme functions.php :

    function av_return_100(){ return 65; }
add_filter('jpeg_quality', 'av_return_100');
add_filter('wp_editor_set_quality', 'av_return_100');

    it seems that this is more than a good compromise between performance and quality
