Top 10 Image Lossless Compression Plugins 2022

Lossless image compression is a big deal; more often than not, the actual image files slow our site down significantly, and slow sites are known to cause a much higher bounce rate and a much lower level of satisfaction.

WordPress bloggers are one of the most widely known writers that utilize many images in their content, especially for sites that list, gallery, and how-to posts daily. The upload folder for pictures can quickly grow so that you can see the load time of each web page serving these images. Perhaps, the process of having to optimize each image manually sounds time-consuming, and people just decide not to do it at all.

Thanks to some bright developers and tools, we have several free and premium WordPress lossless image compression plugins available at our disposal, which we will look at in this post. Please share your methods and techniques for compressing images in the comment section.

Several thousand WordPress users are now using this magnificent plugin to optimize images as they are uploaded automatically. It would be best to keep in mind that this plugin only allows you to have 500 image optimizations every month. This is enough for small/medium sized WordPress blogs.

Instead of adding a full-sized image, you can now compress it and make it lighter for your website. Too many large and high-quality pictures stuffing your page can lower the performance.

This plugin is still worth the wait because it offers more flexibility than others.

    Hello, thank you for summary but I still don’t know which one is the best… WP.Smush.it is good and simple but does not show me the best results.

    1. Gayatri,

      It depends what you mean by “best results”. It offers lossless compression therefore your images will look exactly the same with the same quality but will be smaller in size. If you have uploaded images that has high resolution it won’t help you because it isn’t resizing images but reducing them in size.
