How to Regenerate Thumbnails in WordPress(with plugin)

Are you finding an easy way to regenerate thumbnails in WordPress? Let’s dive into our blog which gives you a simple solution by using a plugin.

Why do you need to regenerate thumbnails in WordPress?

Usually, WordPress utilizes various default image sizes. Therefore, whenever you upload an image to your media library, WordPress automatically creates a thumbnail for it. However, when you change another theme for your website, the problem will occur. All thumbnails still retain the original size on the old theme. As a result, all thumbnails will not fit your new theme. The chaotic thumbnail organization will make your website unprofessional. So, how to handle this problem?

In order to handle this problem, you need to regenerate thumbnails in WordPress. In today’s blog, we will help you tackle this issue via a useful plugin. Now, let’s check them out.

How to regenerate Thumbnails in WordPress via plugin?

The excellent plugin that will help you regenerate thumbnails for all uploaded images to WordPress Media Library is the Regenerate Thumbnails plugin.

Now, you can follow the steps below:

Step 1: Install and activate the plugin

Simply go to Plugins > Add new and then type the plugin’s name on the search bar. After that, you need to locate the plugin and click on the “Install Now” button to activate it later.

Step 2: Configure the plugin’s settings

Once the plugin was activated, you need to navigate to Tools > Regenerate Thumbnails.

On the settings page, you will see two options:

The first option allows the plugin to skip over images that have correctly sized thumbnails. This is a great option, so you should turn on it.
The second option allows you to delete all thumbnail files for deprecated images sizes. This option can help you significantly free up server space. However, you have to regenerate again if you want to regain the original image sizes. It is not a difficult task, so you can check this option.
