<p>Edge Images automatically uses your edge transformation service (e.g., Cloudflare, Accelerated Domains, Imgix, etc.) to apply performance optimizations to <code><img></code> markup.</p>
<p>⚠️ <strong>Important</strong>: This plugin requires a supported edge provider with image transformation features enabled (e.g., Cloudflare Pro, BunnyCDN, etc). See the Requirements section for details.</p>
<h4>🚀 Why should I use Edge Images?</h4>
<ul>
<li><strong>Instant Performance Boost</strong>: Automatically optimize and serve images in modern formats (WebP/AVIF) through your existing CDN</li>
<li><strong>Zero Configuration</strong>: Works out of the box with your existing images and themes</li>
<li><strong>No Local Processing</strong>: All transformations happen at the edge – no server load or storage overhead</li>
<li><strong>Perfectly Sized Images</strong>: Automatically generates the exact image dimensions needed for every device and viewport</li>
<li><strong>Cost Effective</strong>: No need for expensive image optimization services or additional storage</li>
</ul>
<h4>🎯 Perfect For</h4>
<ul>
<li>Sites with lots of images that need optimization</li>
<li>Performance-focused developers and site owners</li>
<li>Anyone using Cloudflare, BunnyCDN, or similar services</li>
<li>Sites that want modern image formats without the complexity</li>
<li>Developers tired of managing multiple image sizes</li>
</ul>
<h4>💡 How It Works</h4>
<p>WordPress typically creates multiple copies of each uploaded image in different sizes. This approach is inefficient and often results in:</p>
<ul>
<li>Images that are too large or small for their display size</li>
<li>Unnecessary storage usage</li>
<li>Missing sizes for modern responsive designs</li>
<li>Lack of modern format support (WebP/AVIF)</li>
</ul>
<p>Edge Images solves these problems by:</p>
<ol>
<li>Intercepting image requests</li>
<li>Determining the optimal size and format needed</li>
<li>Using your CDN to transform the image on-demand</li>
<li>Caching the result for future requests</li>
</ol>

<h4>🛠️ Technical Example</h4>
<p><strong>Your Code</strong></p>
<pre><code>echo wp_get_attachment_image(1, [640,400], false, ['fit' => 'contain']);
</code></pre>
<p><strong>What WordPress Usually Outputs</strong></p>
<pre><code><img width="380" height="400" 
     src="/uploads/2024/11/1.jpg" 
     class="attachment-640x400 size-640x400 wp-image-123" 
     srcset="/uploads/2024/11/1.jpg 400w, /uploads/2024/11/1-285x300.jpg 285w" 
     sizes="(max-width: 640px) 100vw, 640px">
</code></pre>
<p>That’s multiple different images files, none of which are the right size!</p>
<p><strong>What Edge Images Outputs</strong></p>
<pre><code><picture class="edge-images-container" style="--max-width: 640px;">
  <img 
       class="attachment-1140x600 size-640x400 wp-image-123 edge-images-processed"
       width="640" height="400" 
       src="/cdn-cgi/image/f=auto,fit=contain,w=640,h=400/uploads/2024/11/1.jpg" 
       srcset="/cdn-cgi/image/f=auto,w=320,h=188/uploads/2024/11/1.jpg 320w,
               /cdn-cgi/image/f=auto,w=640,h=400/uploads/2024/11/1.jpg 640w,
               /cdn-cgi/image/f=auto,w=1280,h=800/uploads/2024/11/1.jpg 1280w"
       sizes="(max-width: 640px) 100vw, 640px">
</picture>
</code></pre>
<p>That’s a range of perfectly sized options for different devices and viewports, automatically optimized images in modern formats, served from your CDN, futureproofed for supporting next-generation capabilities, and with no storage overheads.</p>
<h4>🎨 Customization</h4>
<p><strong>Transform Parameters</strong><br />
Control every aspect of image transformation with attributes like:<br />
* <code>width</code>/<code>height</code>: Exact dimensions<br />
* <code>fit</code>: Resizing behavior (contain, cover, crop)<br />
* <code>quality</code>: Compression level<br />
* <code>format</code>: Output format (auto, webp, avif)</p>
<p><strong>Filtering</strong><br />
Disable transformations globally or selectively:</p>
<pre><code>// Disable all transformations
add_filter('edge_images_disable', '__return_true');

// Disable for specific images
add_filter('edge_images_disable_transform', function($should_disable, $html) {
    if (strpos($html, 'example.jpg') !== false) {
        return true;
    }
    return $should_disable;
}, 10, 2);

// Override max width for constrained content
add_filter('edge_images_max_width', function($max_width) {
    // Example: Use a different max width for single posts
    if (is_single()) {
        return 800;
    }
    return $max_width;
});

// Customize srcset width multipliers
add_filter('edge_images_width_multipliers', function($multipliers) {
    // Add more granular steps between sizes
    return [0.25, 0.5, 0.75, 1, 1.25, 1.5, 2];
});
</code></pre>

Edge Images


Kinda amazing how simply this just works with Cloudflare.  Definitely use this if you have a pro plan.  


Just worked


Although this is a new plugin, it's been developed and tested over several years and it shows. Dead simple user interface and does exactly what it needs to do with no fuss.


Smashing


I've tried this out with Accelerated Domains and it works like a charm.  Under the hood the code is really easy to understand and well written.  Recommended. 


Works great with Accelerated Domains

Turbocharge your WordPress images by using an edge provider (like Cloudflare or Accelerated Domains) and optimizing your HTML markup.

<h4>What this plugin can do for you</h4>
<p>https://www.youtube.com/watch?v=DWANhxoDxFI?feature=youtu.be</p>
<p><strong>Automatic Platform Optimization (APO)</strong></p>
<p>Speed up your WordPress site by up to 300% with Cloudflare’s Automatic Platform Optimization (APO) plugin. APO allows Cloudflare to serve your entire WordPress site from our edge network of over 250+ data centers worldwide ensuring fast & reliable performance for your visitors no matter where they are.</p>
<p>Optimizing your WordPress site with multiple plugins can be overwhelming. Take your WordPress site’s performance to the next level by switching to a single plugin for CDN, intelligent caching, and other key WordPress optimizations with Cloudflare (APO). Visit our <a href="https://blog.cloudflare.com/automatic-platform-optimizations-starting-with-wordpress/" rel="nofollow ugc">announcement blog</a> to learn more about APO.</p>
<p><strong>What makes APO different from other caching plugins?</strong></p>
<p>The key differentiating factor between Cloudflare APO and other traditional page caching and CDN solutions is its ability to directly cache static HTML at Cloudflare’s edge. Every other plugin and CDN will cache your static assets (images, javascript, CSS), but none help you cache the actual content on your site (the HTML) using a massive edge network like Cloudflare’s.</p>
<p>APO intelligently caches your HTML pages and will automatically purge content from the cache that you update, so users will always see the latest content without compromising the performance of pages that haven’t been recently updated</p>
<p><strong>What you get with Cloudflare APO</strong></p>
<p>APO is a $5 add-on with Cloudflare’s free plan and comes with an unlimited amount of subdomains. With APO you also get to leverage many of the other benefits of Cloudflare such as <strong>Free DNS, Free Automated SSL Certificates, Free DDoS Mitigation, and more.</strong> APO is free for all paid plan users so if you have Cloudflare Pro or Business already you can just turn it on. You can compare all our plans <a href="https://www.cloudflare.com/plans/?utm_source=promo&utm_medium=social&utm_term=&utm_content=&utm_campaign=g421o-pl-apo-wordpress-plans" rel="nofollow ugc">here</a>.</p>
<p><strong>Protect your WordPress site with Cloudflare’s Web Application Firewall (WAF)</strong></p>
<p>Cloudflare’s WAF is available on all our <a href="https://www.cloudflare.com/plans/?utm_source=promo&utm_medium=social&utm_term=&utm_content=&utm_campaign=g421o-pl-apo-wordpress-plans" rel="nofollow ugc">paid plans</a> and comes with built-in rulesets, specifically tailored to mitigate WordPress threats and vulnerabilities. These security rules are regularly updated by our team of experts. At the flip of a switch, you’ll have your WAF up and running without any difficult adjustments to your site. With over 26 million internet properties under our protection, you can sleep easy knowing Cloudflare has your back.</p>
<h4>Additional features</h4>
<ul>
<li>
<p>Header rewrite to prevent a redirect loop when Cloudflare’s Universal SSL is enabled</p>
</li>
<li>
<p>Change Cloudflare settings from within the plugin itself without needing to navigate to the cloudflare.com dashboard. You can change settings for cache purge, security level, Always Online, and image optimization</p>
</li>
<li>
<p>View analytics such as total visitors, bandwidth saved, and threats blocked</p>
</li>
<li>
<p>Support for <a href="https://blog.cloudflare.com/announcing-support-for-http-2-server-push-2/" rel="nofollow ugc">HTTP2/Server Push</a></p>
