Using images to visualize, advertise and overall, improve your content and blogs is an essential procedure for your website. But users have to be aware of the disadvantages of using too many images on your posts and pages. For one, it decreases the free space on your server. Ideally, you want to save your images on your own website’s server so that you can save and delete the images whenever required. This also improves the loading speed compared to using third-party image gallery websites.
Having too many images on a single post and page can also increase loading time for the webpage, as this means the client pc has to load bigger files to view your post. This can discourage a more impatient crowd and you really don’t want viewers to leave your website without even taking a look. Do you? Obviously not! Thus, in this article, we have listed down the best free WordPress image optimizers to make the optimization task fuss-free.

In order to decrease the size of your images, we can optimize the images by compressing the image without causing a significant drop in image quality. From image resizing to removing image information, and changing image extensions, we can do them.
