Autoptimize vs Edge Images

Autoptimize makes optimizing your site really easy. It can aggregate, minify and cache scripts and styles, injects CSS in the page head by default but can also inline critical CSS and defer the aggregated full CSS, moves and defers scripts to the footer and minifies HTML. You can optimize and lazy-load images (with support for WebP and AVIF formats), optimize Google Fonts, async non-aggregated JavaScript, remove WordPress core emoji cruft and more. As such it can improve your site’s performance even when already on HTTP/2! There is extensive API available to enable you to tailor Autoptimize to each and every site’s specific needs. If you think performance indeed is important, you should at least consider one of the many free page caching plugins (e.g. Speed Booster pack or KeyCDN’s Cache Enabler) to complement Autoptimize or even consider Autoptimize Pro which not only has page caching but also image optimization, CDN, critical CSS and more! Autoptimize Pro Autoptimize Pro is a premium Power-Up, adding image optimization, CDN, page caching, automatic critical CSS rules and extra “booster” options, all in one handy subscription to make your site even faster!!

Edge Images automatically uses your edge transformation service (e.g., Cloudflare, Accelerated Domains, Imgix, etc.) to apply performance optimizations to markup. ⚠️ Important: This plugin requires a supported edge provider with image transformation features enabled (e.g., Cloudflare Pro, BunnyCDN, etc). See the Requirements section for details. 🚀 Why should I use Edge Images? Instant Performance Boost: Automatically optimize and serve images in modern formats (WebP/AVIF) through your existing CDN Zero Configuration: Works out of the box with your existing images and themes No Local Processing: All transformations happen at the edge – no server load or storage overhead Perfectly Sized Images: Automatically generates the exact image dimensions needed for every device and viewport Cost Effective: No need for expensive image optimization services or additional storage 🎯 Perfect For Sites with lots of images that need optimization Performance-focused developers and site owners Anyone using Cloudflare, BunnyCDN, or similar services Sites that want modern image formats without the complexity Developers tired of managing multiple image sizes 💡 How It Works WordPress typically creates multiple copies of each uploaded image in different sizes. This approach is inefficient and often results in: Images that are too large or small for their display size Unnecessary storage usage Missing sizes for modern responsive designs Lack of modern format support (WebP/AVIF) Edge Images solves these problems by: Intercepting image requests Determining the optimal size and format needed Using your CDN to transform the image on-demand Caching the result for future requests ⚡️ Features Core Features Automatic WebP/AVIF conversion Intelligent responsive image handling Smart srcset generation Automatic image optimization Optional element wrapping Zero local processing Maintains original images Advanced Features Fine-grained transformation control Multiple CDN provider support Developer-friendly filters Yoast SEO & Rank Math integrations Bricks integration Gutenberg compatibility 🔌 Supported Providers Cloudflare (Pro plan or higher) Accelerated Domains BunnyCDN Imgix 🛠️ Technical Example Your Code echo wp_get_attachment_image(1, [640,400], false, ['fit' => 'contain']); What WordPress Usually Outputs That’s multiple different images files, none of which are the right size! What Edge Images Outputs 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. 🎨 Customization Transform Parameters Control every aspect of image transformation with attributes like: * width/height: Exact dimensions * fit: Resizing behavior (contain, cover, crop) * quality: Compression level * format: Output format (auto, webp, avif) Filtering Disable transformations globally or selectively: // 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]; }); 🔧 Requirements Essential A supported edge provider with image transformation features enabled: Cloudflare Pro plan or higher with Image Resizing enabled Accelerated Domains with Image Resizing enabled BunnyCDN with Image Processing enabled Imgix with a configured source Technical PHP 7.4 or higher WordPress 5.9 or higher ✅ Getting Started Install and activate the plugin Go to Settings > Edge Images Select your CDN provider That’s it! Your images will now be automatically optimized 🤝 Integrations Yoast SEO Automatically optimizes images in: Meta tags (og:image, etc.) Schema.org output XML sitemaps 🔒 Privacy Edge Images processes images through third-party edge providers. Here’s what you need to know about privacy: Data Processing Images are processed through your chosen edge provider (Cloudflare, Accelerated Domains, etc.) No personal data is collected or stored by the plugin itself Image URLs are passed to the edge provider for transformation Original images remain on your server; only public URLs are processed Edge Provider Privacy Different providers have different privacy implications: Cloudflare: Images are processed according to Cloudflare’s Privacy Policy Accelerated Domains: Images are processed according to Accelerated Domains’ Privacy Policy BunnyCDN: Images are processed according to BunnyCDN’s Privacy Policy Data Storage The plugin stores your selected settings in your WordPress database No user data is collected or stored No analytics or tracking is performed Cache files may be created in your uploads directory for optimization GDPR Compliance The plugin is GDPR-compliant as it does not collect, store, or process personal data Users should review their chosen edge provider’s privacy policy and data processing terms Site owners should update their privacy policy to reflect their use of third-party image processing services Development GitHub Repository Report Issues
