We assume that you learned already about WebP image format Google created. You generated WebP versions of your files with a smart tool – we assume that it was ShortPixel. And, finally, you employed a plugin (like wp-webp) to deliver the WebP images to users who visit your site from a compatible WebP-compatible browser (Chrome and Opera, mainly, a full list is to be found here).
What’s next? Of course, you want to test if everything works as expected. The easiest method to see if your website has WebP images has three simple steps:
Step 1: Open your site in Chrome browser.
Step 2: Right-click on an image and choose Open in new tab.

Step 3: Check the image extension.
If it is .webp, then we only could congratulate you. And Google will love your site a bit more!
