Optimizing images on your site is very important in order to make your site perform well.

Crafting your website is like writing a book. Along with all the text, you also have to put in media files. And depending on the media files and their size, the load speed of your site will get affected. This is quite intuitive in consideration to videos. 

We all know that having videos on our site will decrease the load speed. But often we fail to evaluate the same for the pictures that we use.

Images are not light file types. And that goes more for high-resolution image files. This is surely a problem. However, this doesn’t call for compromising on the number of images you intend to use. In fact, use as many as you like, but get them OPTIMISED.

So if you are using WordPress, here we will be discussing some powerful image optimization plugins which can compress the images and also help out SEO. So without further ado, here are the 8 Best Plugins to Optimize Images.
