Why Do You Need Image Optimization Plugins for Your WordPress Site?

Images on your website make your content more engaging for readers. They’re a must-have on your site if you want your visitors to stick around long enough to become customers. But images are much larger in size than plain text. Because images are so much larger, they can slow your website’s speed down to a snail’s pace.

Having a speedy website is important. Users today have no time or patience to sit around and wait for your website to load. In fact, 47 percent of customers expect a web page to load in 2 seconds or less. So, if your website doesn’t load fast enough, users will abandon your site in search of someone else’s.

But what can you do to speed up your site while keeping your important images? That’s where image optimization plugins come in.

To improve the speed of your WordPress site, you need to optimize your images. Image optimization plugins can optimize your images for you automatically, so you don’t have to know a thing about photo editing or code. And you don’t have to worry about sacrificing the quality of your images either.

Not only does optimizing your images help with speeding up your website, it also improves your search engine optimization (SEO) as well.

All of these image optimization plugins will optimize the photos on your site so that your WordPress website is speedier and your site gets found more easily by users searching the web.

Get ready to make your website lightning fast. Check out our list of the best image optimization plugins for WordPress.
