By using the right WordPress plugin, you can automate the conversion process, manage your media library seamlessly, and deliver optimized images to your visitors in real time. In this article, we will explore the best WordPress plugin that allows you to automatically convert images to WebP.
First, let’s see what WebP images are.

What Are WebP Images
A WebP image is a modern image format developed by Google’s web team to improve loading speed and overall WordPress performance.
It is designed to convert traditional JPEG images into compressed images that are much smaller in file size while still looking sharp. This reduction helps websites load faster, improves user experience, and supports better optimization compared to older image formats.
WebP supports both lossy and lossless compression, which means developers and site owners can choose between maximum size reduction or higher visual quality.
When you convert images to WebP on WordPress, the goal is to compare the original format with the new WebP format and achieve a significant reduction in image size without breaking the design.
Most modern browsers now provide full browser support for WebP, so images can be displayed correctly across devices and themes.
Why Should You Convert Images to WebP on WordPress
Converting images to WebP helps you optimize your site without touching the core design or layout. It is a simple option that works with most WordPress themes and plugins and can be enabled through a basic setting after you install an image optimization plugin.
Smaller image files mean your host uses fewer resources, which helps maintain site stability and improves real-time delivery of content to visitors.
Using WebP also makes it easier to measure performance improvements because reduced image size saves data and speeds up page loading. Faster pages work best for user experience and can help your site rank better in search results.
This matters for long-term growth because optimized images reduce traffic strain on your server and improve how browsers load CSS and other assets connected to your images. Another benefit is how practical the process is for everyday site management.
You can convert images with a single click from the dashboard, often using a clear button or tab inside the plugin interface.
Now you know why you should convert images to WebP on WordPress. Next, let’s see how to automatically do it.
How to Automatically Convert Images to WebP on WordPress
There are several plugins available to automatically convert images to WebP on WordPress. For this tutorial, we will be using the WebP Converter for Media plugin.

It is a free WordPress plugin that you can get from the repository. The first thing you need to do is install and activate the plugin.

Once you have finished the activation, you can see the plugin’s settings under the WordPress settings section.

There, you can see three main configuration options.
- General settings
- Advanced settings
- CDN settings

Let’s see what each option has to offer.
1. General Settings
If you are using the free version of the plugin, you can only convert the images to WebP. AVIF conversion is only possible in the premium version. Once you have done that, choose the conversion strategy and the directories you need to compress.

Now scroll down, and you can see the automatic conversion option.

2. Advanced Settings
Here, you can choose the file extensions you need to convert. Also, you can see the option to exclude specific directories from optimization.

Now, you have to choose the conversion method, image loading mode, and extra features.

3. CDN Settings
Here, you can complete the Cloudflare integration.

Save the changes once you are done with it.
From now on, all the new image uploads will be converted to WebP. You can also convert your existing images to WebP via the general settings page.
