Every time you upload an image, Simple WebP generates a .webp version. It then alter the HTML to replace img tags with picture tags, which let the browser pick the best format.
WebP images are often smaller than original .jpeg or .png one, so can save bandwidth and load time. Most browsers support WebP nowadays. You can use <a href="https://developers.google.com/speed/pagespeed/insights/" rel="nofollow ugc">Google Pagespeed</a> tool to see the gain you would get from WebP.
You will get much faster load time, and better ranking in Google Search.
Simple WebP is very much inspired by the more complete (and complex to install) <a href="https://fr.wordpress.org/plugins/webp-express/" rel="nofollow ugc">WebP Express</a> plugin. It also use the same libraries :
<ul>
<li><a href="https://github.com/rosell-dk/webp-convert" rel="nofollow ugc">WebPConvert</a>: For converting images to webp</li>
<li><a href="https://github.com/rosell-dk/dom-util-for-webp" rel="nofollow ugc">DOM Util for WebP</a>: For the Alter HTML functionality</li>
</ul>

Simple WebP

For every image uploaded, Simple WebP creates a WebP version which is served to compatible browsers.

<h3>Why It Matters</h3>
In 2025, website performance is non-negotiable. Google prioritizes fast-loading sites, and users expect instant access. With ImageOptimizerX, you’re not just optimizing images—you’re optimizing your entire online presence. Don’t let unoptimized media slow you down—take control today!
By deeply optimizing your images, ImageOptimizerX becomes a powerful ally for improving both SEO and overall site performance. Search engines prioritize Core Web Vitals, and lighter, efficiently compressed images play a crucial role in achieving strong LCP and FID scores. When paired with popular caching plugins—such as WP Super Cache, W3 Total Cache, LiteSpeed Cache, or any modern performance optimizer—ImageOptimizerX delivers a double speed boost: the cache serves already-optimized, lightweight images, resulting in near-instant page loads. This combination helps your site rank higher in search results, reduce bounce rates, and deliver a significantly smoother user experience, especially on mobile devices.

I am very happy with it and I don’t need to read long instructions. The plugin made my images smaller without losing quality, and now my site load more faster, especially on mobile. I also like that it works well with other plugins I have, no conflict or problems. I use free version and it already give many good features. This plugin saved me time because I don’t need to optimize images one by one. Definitely recommend it to others.
