WordPress image optimization is one of the most effective ways to boost your overall site speed.
Images are a big part of your website. They help attract readers to your posts, and make content more interactive.

Plain text and HTML code loads instantly, but you’re often left waiting for one bloated image to arrive from the server.

The easiest way to condense your images is with a WordPress image optimization plugin. These plugins use a variety of techniques to reduce the size of your images, or at least offset the time users spend waiting on images to load.

What is WordPress Image Optimization Important?
Optimizing your images will make your site’s load time significantly shorter.
This is done by reducing the files size of images, by reducing the resolution to what is needed and by stripping metadata (information such as when the picture was taken, what device was used etc).
Not only does it help your site load faster, but well optimized images can also help boost your Search Engine Optimization as your site speed increases. Google likes fast sites, as evidenced by their Core Web Vitals report. As a result, bloated sites that take too long to load tend to rank lower in Google search.
You can also use images to rank well through adding alt and title tags to your images. If these tags are filled with keywords relevant to your article, it will be easier to find on a search engine, as they pick out key words when search the web. This is just another part of ensuring your images are well optimized.
Do You Really Need a Plugin?
You can do WordPress image optimization manually – reducing the file size of any images before you upload them to your site. But if you’re publishing a lot of content, this means a lot of images, and thus a lot of work to optimize every single one.
It’s best to automate this with a WordPress plugin. However, there are a couple of things you should check your own, before you upload images:
- Your images are only as big as they need to be. The file sizes of images on your webpage can greatly affect the loading speed of your page. For example, unnecessarily large images, with big resolutions will take up resources, and ultimately will slow down the loading speed of your page. If these images can be set to a lower resolution, or compressed to be a lower file size, then this will speed up your website. To do this, images can be compressed, so that unnecessary information is no longer included, such as capture date and type of camera used.
- Your images are given relevant names. This will boost your SEO. Images with relevant names will be more likely to appear in search engines, thus optimizing your post, and directing traffic to your blog. This can be done simply, by adding a keyword into the title of the image.
After this, you can rely on an image optimization plugin to cut down the image files served to only what’s absolutely necessary.
