WordPress WebP Images - How to Use it to Speed Up Your Site

Using WordPress WebP images on your site is a great way to break up the text and keep your readers engaged.

But this engagement comes at a cost. The larger the size or number of images, the slower the load time will be. Consequently, this slower speed can affect search engine performance and engagement.

This is why many top WordPress websites adopt the WebP format to optimize their sites. So in this article, you will learn about WordPress WebP images and how to increase the speed of your website.

What Is WebP?

The WebP image format was created by Google in 2010 for web use. The format offers high-quality and rich images in smaller sizes.

When you convert the images on your site to WebP, they will be a lot smaller with no loss in quality.

The conversion can shrink the image size by 25–35%, according to a Google WebP compression study. This would, consequently, increase your site’s speed and your search engine ranking.

Further, WebP image optimization has various levels. You can choose from either the ‘lossy’ or ‘lossless’ compression options.

The lossy compression option preserves more data, while ‘lossless’ makes the image smaller. WebP is also supported by over 90% of browsers, according to caniuse.

Benefits of Using WebP Image

Here are some of the reasons to adopt WebP images in WordPress:

1. Smaller Image File Size

WebP images are smaller compared to other formats. As mentioned above, the conversion can reduce your image size by up to 35%. This means you’re better off using WebP images for your WordPress website than JPEG and PNG images.

2. Increases Page Speed

WordPress WebP images can increase the speed of your web pages. The heavier your pages are, the less time it will take to load. The ideal load speed is 2 seconds or less. This is because customers are likely to abandon a website that takes more than 2 to 3 seconds to load.

3. High-quality Files

The best thing about the WebP format is that it preserves its quality. This means you won’t need to worry about image quality when converting your images.

4. Better Search engine ranking and click-through rate

Page loading speed is a vital factor for search engine ranking and click-through rate. Data from Google’s research shows that a page load time of more than 3 seconds increases the chance of a bounce by 32%. 

A load time of 5 seconds or more increases the chances of a bounce by 90%. Your website will rank higher once you increase the speed by converting the images to WebP. This will also result in a lower bounce rate.

5. Reduce Bandwidth Usage

Website bandwidth is the amount of data that can be transferred between a site, its users, and its servers. Having limited bandwidth can result in slower loading speeds. So adopting WebP can free up more bandwidth space and increase the speed of your site.

How to Enable WebP Images to Speed Up Your Site

Using WebP images on your WordPress site is just as simple as using other formats like JPEGs and PNGs. WebP is supported by default on WordPress 5.8 and above.

This means that you don’t need any configurations to use WebP images in WordPress version 5.8 and above.

So if you have WebP images, you can upload them to the WordPress Media Library. But if you don’t have images in WebP format, you may have to manually convert the image to WebP before uploading.

You can also automate this process by installing a WordPress WebP Image plugin.

How to Automate WebP Images With a WordPress Plugin

There are several WordPress WebP plugins to convert images to WebP format. Most of these plugins support WebP fallback redirection. This ensures that people with browsers that don’t support WebP get the original format.

For example, if you upload a JPEG file to your site, the plugin will convert it to WebP format. This way, if the visitors are using a browser that supports WebP, they will be served the WebP versions.

Otherwise, they will get the original image format, whether it is JPEG or PNG. This ensures that everyone gets the fastest experience possible.
