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 or why not, the same ShortPixel!) to deliver the WebP images to users who visit your site from a compatible WebP-compatible browser (mainly all except IE and Safari; 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!

Great, you know more about WebP format than some SEO specialists!
WebP – to use or not to use?
If you SEO is almost an unhealthy obssesion, then you surely need WebP images 🙂 For the rest of the folks, the answer is Maybe. The ability to serve WebP files is a nice to have feature from a SEO point of view.
There is a “but”: please remember that WebP is not a universal format. Safari and Internet Explorer don’t understand it, and you need enough hosting storage to keep JPEG/PNG versions of your images alongside the WebP ones. Moreover, you depend on a caching or special plugin to deliver the right images to the right browsers.
More storage and more plugins, this is the price for having WebP files. You should decide whether if it’s worth it. The good news is that ShortPixel can freely generate the WebP version of your images and at the same time compresses your pictures. It is not bad to have your JPEG/PNG images optimized alongside WebP 🙂
What image format does ShortPixel.com use?
ShortPixel preferred formats are: PNG for screenshots&logos and JPEG for the rest of the images. Of course, SEO is important for us too. That’s why we developed Lossy optimization, which generates compressed images at a very good quality, and Glossy optimization for images looking almost identical with the originals.
Right now, we use Glossy*, because we want to have optimized images with the best picture quality, instead of stretching a few more bits for Google.
