<li>Optimised for your site to rank.</li>
<li>CLI to regenerate all of your media files.</li>
<li>Helper functions to output images in templates.</li>
<li>Uses the native <code>cwebp</code> and <code>libavif</code> libraries.</li>
</ul>
<h3>What does Squidge do?</h3>
Squidge compresses and converts image files when the user has uploaded a file to WordPress.
<ul>
<li>Compresses JPG images using <code>jpegoptim</code>.</li>
<li>Compresses PNG images using <code>optipng</code>.</li>
<li>Converts JPG and PNG images to <code>.webp</code> files using <code>cwebp</code> with the appended extension e.g. <code>image.jpg.webp</code>.</li>
<li>Converts JPG and PNG images to <code>.avif</code> files using <code>libavif</code> with the appended extension e.g. <code>image.jpg.avif</code>.</li>
</ul>
<h3>Render Images</h3>
To render images in templates, you can either set up nginx or apache rules to serve images dynamically or used the 
 squidge_image helper function. This dynamically checks if an <code>.avif</code> or <code>.webp</code> file is available on the file system 
and returns the output.
<h3>Function</h3>
<pre><code>/**
 * Returns a <picture> element with source media for the standard file passed
 * (such as a JPG), the .avif file, the .webp file (if to exist on the file system).
 *
 * Appropriate <source> elements for image sizes with max widths.
 * Finally, the main be outputted with alt and title text.
 *
 * - If lazy is true, the data-src or data-srcset will be appended.
 * - If a class is set, the class will be outputted on the <picture> element.
 *
 * @param $image_id
 * @param string $class
 * @param false $lazy
 * @return string
 */
function squidge_image($image_id, $class = '', $lazy = false)
</code></pre>
<h3>Output</h3>
<pre><code><picture class="picture">
 
 <source media="(max-width: 400px)" srcset="/sample-image.jpg.avif" type="image/avif">
 <source media="(max-width: 400px)" srcset="/sample-image.jpg.webp" type="image/webp">
 <source media="(max-width: 400px)" srcset="/sample-image.jpg">
 
 <source srcset="/sample-image.jpg.avif" type="image/avif">
 <source srcset="/sample-image.jpg.webp" type="image/webp">
 
 <img src="/sample-image.jpg" alt="Alt text" title="Sample JPG">

<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.
