The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.

    • Original 645.9 kB
    • After minification 562.0 kB
    • After compression 185.8 kB

    JavaScript optimization

    It’s better to minify JavaScript in order to improve website performance. The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 460.0 kB or 71% of the original size.

    • Original 432.0 kB
    • After minification 428.3 kB
    • After compression 68.0 kB

    CSS optimization

    CSS files minification is very important to reduce a web page rendering time. The faster CSS files can load, the earlier a page can be rendered. Ciw.edu needs all CSS files to be minified and compressed as it can save up to 364.0 kB or 84% of the original size.
