How to Use WebP Images on WordPress

Continuing this theme, we want to add that it is important to remember those 22 percent of users who are not able to view WebP images. In this part of the blog, you would see how you can use WebP Images on WordPress.

It’s important for all users who use browsers with WebP images SUPPORT and those without browsers support to get a wonderful user experience and see images on your site.

Since some users do not have access to the WebP format, you cannot upload them in the WebP image format and use them on the site, like you would for JPEG and PNG. If you do this, then those 22 percent will see no picture.

The best way out of this situation is to use WordPress plugins. The plugins allow you to display WebP Images on WordPress for those whose browser supports this, or display the same image in different formats for all other users.

Should I use WebP images on WordPress?

We think that using WebP images on WordPress is a prerequisite for a successful and fast website today. Nowadays, the two things that are most valued are:

  1. time
  2. quality

Another valuable tip!

To understand the best image format to use, just look at which browsers your visitors are using.

Here's an example of analytics for you:

Google analitics to see browsers visitor use

As we can see in the screenshot 68% of the visitors use Chrome, that means they can open WebP. The second and third places are occupied by Internet Explorer and Safari. That means that there is a need to use the fallback image option so that other users can open images.

Even if Apple does not support the WebP format, this hat doesn’t mean you shouldn’t use it. WebP has so many benefits that we would advise everyone to use it.

If your page is visited by users of those browsers that do not support WebP, then JPEGs and PNGs formats will be available for them.

This way all users can see the image, regardless of the type of browser. It's just that those who will open WebP formats will be able to load your page faster.

If you convert WebP images you can kill two birds with one stone. The smaller images you use on a page, the faster it will load.


Using WebP Images on WordPress is an opportunity to speed up your page load speed while maintaining the quality of your images.
