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.

Skyspeed is a robust, enterprise-grade image optimization solution designed to make your WordPress site lighter and faster without sacrificing visual quality.
Unlike other plugins that bloat your dashboard with upsells, Skyspeed is focused purely on performance. It automatically intercepts every image you upload, resizes it to a sane maximum width, and converts it to modern, high-compression formats like AVIF and WebP.
<h3>🚀 Key Features</h3>
<ul>
<li>Smart Format Selection: Automatically checks if your server supports AVIF (the newest, most efficient format). If not, it falls back to WebP, and finally to the original format if needed.</li>
<li>Intelligent Resizing: Automatically resizes massive uploads (e.g., 6000px wide photos from phones) to a web-ready Max Width (default: 1920px), saving megabytes instantly.</li>
<li>Safety First (Automatic Backups): We care about your data. Every original image is safely backed up to a dedicated folder (<code>uploads/original-backups/</code>) before any optimization occurs.</li>
<li>One-Click Restore: Made a mistake? Hover over any image in the Media Library and click “Restore Original” to revert instantly.</li>
<li>Bulk Optimizer: Process your entire existing media library in the background with our AJAX-powered batch processor. Includes a sleek circular progress bar!</li>
<li>Live Preview: Don’t guess quality settings. Use the Live Preview tool to compare “Before vs. After” quality and file size on a real image before applying settings globally.</li>
<li>Analytics Dashboard: Track exactly how much disk space you’ve saved with our built-in savings calculator and dashboard widget.</li>
</ul>
<h3>⚡ Why AVIF?</h3>
AVIF is the successor to WebP. It offers superior compression (often 20-30% smaller than WebP) with better visual fidelity. Skyspeed is one of the few free plugins that prioritizes AVIF support out of the box.
