Page optimization

  • HTML 246.2 kB
    Images 2.7 MB
    Javascripts 1.2 MB
    CSS 1.0 MB

    In fact, the total size of main page is 5.2 MB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 80% of websites need less resources to load and that’s why Accessify’s recommendations for optimization and resource minification can be helpful for this project. Images take 2.7 MB which makes up the majority of the site volume.

    • Original 246.2 kB
    • After minification 241.4 kB
    • After compression 61.5 kB

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 871.6 kB or 74% of the original size.

    • Original 1.0 MB
    • After minification 1.0 MB
