Page optimization

  • HTML 48.1 kB
    Images 751.3 kB
    Javascripts 588 B
    CSS 5.2 kB

    • Original 48.1 kB
    • After minification 40.4 kB
    • After compression 10.2 kB

    HTML optimization

    HTML content can be minified and compressed by a website’s server. The most efficient way is to compress content using GZIP which reduces data amount travelling through the network between server and browser.

    • Original 588 B
    • After minification 361 B
    • After compression 225 B

    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 363 B or 62% of the original size.

    • Original 5.2 kB
    • After minification 3.5 kB
    • After compression 1.6 kB
