10 Best WordPress Image Optimization Plugins

We are all aware of the impact of high-quality and beautiful images on the attractiveness of websites, but this is not a reason to slow down the loading speed of the pages of our WordPress site due to the use of a large number of high-quality images. Slow loading speed equals user and search engine dissatisfaction, and you certainly don’t want that if you’re looking to improve your SEO rankings. This is where WordPress image optimization plugins come into play.

Using image optimization tools in WordPress is one of the best ways to improve website speed and improve user experience, the most popular of which are EWWW Image Optimizer, Smush and ShortPixel Image Optimizer.

Although there are many methods such as Photoshop, WordPress internal editor software, using CDNs, lazy loading technique, image cache, etc., which you can use to edit your website images, but you who use WordPress are much luckier.

This platform has many plugins that you can use by the rule “a picture is worth a thousand words”. Go ahead and add images of your choice to your content. This is where you won’t suffer from slow loading speed and your site visitors won’t see plain, soulless textual content, and it’s a win-win.

Of course, it’s not a good idea to just stick to image optimization plugins. Maybe at the beginning of the work, when the amount of content and traffic of the site is less, you will achieve the desired result, but you will certainly face a series of problems later, such as a drop in speed and performance. The best idea is to use a powerful server with high memory and processing power to host your website content.
