Before we dive into the installation and features of this WordPress image optimization plugin, let’s have a look at why image optimization is crucial for your website performance.

Why is it advisable to optimize images on your WordPress website?

You may not know that each image on your website sends the individual HTTP request to the header, and that’s why optimizing the images will provide you with the following benefits:

  • It improves the loading speed of your website, which ultimately enhances the user experience.
  • Reduced image sizes mean reduced load on the server and extra storage space.
  • It saves the cost of hosting by reducing the network bandwidth.

So optimized images are not only good for the users but your website performance and ranking. WP Smush works seamlessly with the Google PageSpeed Insight Tool and resolves all the image loading issues. It automatically compresses all the images on your website.

Key features of the WP Smush image optimization plugin

WP Smush is the award-winning image compression and image optimization plugin for WordPress. It has been tested many times for quality and speed. Let’s have a look at some of its prominent features:

Lossless Compression

The free version of this WordPress plugin only offers lossless compression. It is already activated in the default settings. These features compress your images without reducing the quality and also strip idle data. It only reduces the size only by 5 to 6%.

You can see a significant improvement in the GTmetrix score even with the small reduction. But it doesn’t reduce the overall page size significantly.

Lazy Loading with WP Smush

WP Smush also offers the Lazy loading feature, and it is enabled by default. Lazy loading increases the page loading speed by keeping off the screen images from loading. It also benefits the users, as it saves bandwidth for those who don’t scroll a complete page.

Content Delivery Network (CDN)

The Smush CDN is a perfect option unless you need a custom domain with a dedicated CDN service. Once you will enable their CDN, all your image URLs will be rewritten, and the plugin will serve the images from global networks.

WebP integration

The CDN comes with the WebP integration. It means that if your browser supports the WebP, the smush will serve all the images in that format. This feature is only available if you enable their CDN.

Super Smush or Lossy Compression (Pro version)

Super Smush is only available in the premium version. It is an advanced technique to compress the images up to 60%.  They say that Lossy compression offers a 2x reduction, but we believe it is more than that. If you want to save significant bandwidth, this feature is for you.

Other key features of the WebP Smush are as follow:

  • With one click, optimize and compress approximately 50 images at a time.
  • Select a maximum width and height to scale the large images.
  • Optimize the images which are 5Mb in size at no cost and without any limit.
