Image Optimization for Best Web Performance in 2022

Here’s what Google says about browser caching:

HTTP caching can speed up your page load time on repeat visits.

When a browser requests a resource, the server providing the resource can tell the browser how long it should temporarily store or “cache” the resource. For any subsequent request for that resource, the browser uses its local copy, rather than going to the network to get it.

You may even see this warning in Google PageSpeed Insights if your website could benefit from browser caching:

In WordPress, it’s pretty straightforward. Just install a plugin like W3 Total Cache or Leverage Browser Caching. That will enable browser caching by default and add the required modifications to your .htaccess file.

For non-WordPress users, you will need to add this code to your .htaccess file manually:

<IfModule mod_expires.c>
ExpiresActive On
# Images
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
</IfModule>

You can change the “1 year” part to “1 month,” “1 week,” “1 day,” “1 hour,” etc.

  • Use vector images whenever possible alongside your PNGs and JPGs.
  • Use a CDN to serve up your images fast to visitors across the globe.
  • Save your images in the proper dimensions. 
  • In some cases, you might want to lazy load images for faster first-page render.
