How To Optimize Images In WordPress For Free

Optimizing your websites images will give your visitors a better experience and give you a boost in Google search results. Here’s how to do it with a free plugin.

Install The Plugin

In your Admin Dashboard hover over Plugins and click on Add New.

In the Keyword Search Box type in ShortPixel.

On the left find the ShortPixel plugin. At the time of this writing it’s got over 200,000 active installs and 4.5 star average reviews.

Click the Install Now Button and then when it turns into the blue Activate button click on that.

Setting Up The Plugin

Once installed you’ll be taken to the ShortPixel Settings page. Because this plugin will send your images to their servers to optimize them we need a free API key. Click on the text link near the top to be taken to the ShortPixel website.

Enter your email address and click the Terms Of Service checkbox before clicking the Get API Key button.

On the next screen you’ll be given your API key. Copy it…

and paste it to the form on in the ShortPixel settings on your site. Then click the blue Validate button.

Optimize Your Existing Images

We now need to go to the media library so we can optimize the images already on the site.

Hover over Media in the left navigation, then click on Library.

If you’re not in List View you will see this message at the top asking you to switch to list view.

We now can click on the blue buttons to the right of each image.

It’s important to note that ShortPixel gives you 100 free images a month and that includes thumbnails, so if an image has 3 thumbnails that would take a total of 4 image credits.

Click on the blue Optimize Now button next to the images you would like ShortPixel to optimize. In a few moments you’ll see the following.

This tells you how much the images was reduced by and that the thumbnails were also optimized.

If you run out of credits you can always buy a monthly plan from ShortPixel or do like I do and buy a one-time purchase of a large set of credits that never expire. You can see their pricing by clicking here.

With the ShortPixel plugin active your images will automatically be optimized when you upload them to your site as long as you have credits available.

If this was confusing in anyway be sure to watch the video tutorial as it’s often easier to explain a step by step process in video format.

I hope this has helped you speed up your site and give your visitors, and search engines, a better experience.
