This article will be updated frequently, so be sure to bookmark it!
Let's start
.webp images
Use the .webp image format to make images smaller and boost the performance of your website.
<picture>
<!-- load .webp image if supported -->
<source srcset="logo.webp" type="image/webp">
<!--
Fallback if `.webp` images or <picture> tag
not supported by the browser.
-->
<img src="logo.png" alt="logo">
</picture>
Lazy loading of the images
You can use the loading=lazy attribute to defer the loading of the image until the user scrolls to them.
<img src='image.jpg' loading='lazy' alt='Alternative Text'>
Fonts requests optimizing
You can specify a text= value in your font request URL to reduce the size of the font file by up to 90%.
<!-- Instead of loading the whole font -->
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Comfortaa">
<!--
Load only what you will use.
Super useful when you're using a web font in a logo or heading
-->
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Comfortaa&text=Hello">
