5 WordPress image optimizer plugins

image optimizer

An important practice for your website is the use of photographs to visualize, advertise and, in general, enhance your content and blogs. But the drawbacks of using so many images on your posts and pages must be understood to users. For one, it decreases your server’s free space. Ideally, you want to save your photos on the server of your own website so that, whenever needed, you can save and remove the photos. Compared to using third-party picture gallery websites, this also increases the loading speed.

It can also increase loading time for the website by getting so many photos on a single post and page, since this implies that the client pc must load larger files to access the post. This can discourage a more anxious crowd because, without even taking a look, you just don’t want viewers to leave your website. Have you? Clearly not! Thus, in this post, to make the optimization task fuss-free, we have listed the best free WordPress image optimizers.
