  • After minification 80.6 kB
  • After compression 17.4 kB

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. This page needs HTML code to be minified as it can gain 187.1 kB, which is 70% of the original size. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 250.2 kB or 93% of the original size.

JavaScript Optimization

-0%

Potential reduce by 162 B

  • Original 57.7 kB
  • After minification 57.7 kB
  • After compression 57.6 kB

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. This website has mostly compressed JavaScripts.

CSS Optimization

-12%

Potential reduce by 375 B

  • Original 3.2 kB
  • After minification 3.2 kB
  • After compression 2.8 kB

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. Qt.io needs all CSS files to be minified and compressed as it can save up to 375 B or 12% of the original size.

After Optimization

23

  • AJAX
  • Images
  • JavaScript
  • CSS

The browser has sent 44 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Qt. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 18 to 1 for JavaScripts and from 5 to 1 for CSS and as a result speed up the page load time.
