WP Smush - The Most Popular Image Optimizer Plugin to Increase Your Web SEO (Review 2021)

Maintaining your website performance to always be in the best shape is very important. This includes optimizing images periodically. You need to know that the images on your website posts can significantly slow down your website. Therefore it is crucial to get your images optimized for your website. 

Why optimize images?

Inserting images affects the readability of your posts. They enhance your site’s appearance, have a role to show off your products or work, and many more. However, the more images you have on your website, the heavier the browser’s work to load your pages. As the result, it slows down your websites whenever any visitors visit them. 

The reason why images can slow down your websites is because of the large sizes of images. When you keep uploading big-sized images, all that data are compiled and takes up your website’s space. Consequently, your sites are slowing down. 

The solution for this problem is image optimization. Plugins that perform image optimization make it possible for you to optimize your site for both performance and (image loading) speed, without requiring you to delete them from your website. This includes sizing images to the correct dimensions, compressing them, and serving them in WebP or other modern formats. This process makes your websites load faster for sure.
