    Image optimization

    Image size optimization can help to speed up a website loading time. The chart above shows the difference between the size before and after optimization. Physics Ox images are well optimized though.

    • Original 153.1 kB
    • After minification 118.2 kB
    • After compression 42.5 kB

    JavaScript optimization

    It’s better to minify JavaScript in order to improve website performance.
