Edge Images vs BoltAudit – Site Speed Audit and Performance Insights

BoltAudit is a read-only speed audit for WordPress. It scans your site, names the specific plugin, query, asset or database table making it slow, and gives you the measured evidence and the ordered steps to resolve each one. Most speed plugins hand you a score and a checklist. BoltAudit names the thing responsible: a plugin not updated since 2019, 41 images above the fold adding up to 4.2 MB, 12,438 post revisions in your database. It estimates what each costs you in visitors and orders them by what you win back. What BoltAudit does, and what it does not BoltAudit finds the work and ranks it. It does not change your site. Every audit is read-only. You get the finding, the evidence behind it, and ordered steps you can follow or hand to a developer. What happens to your site stays your decision. What the free Local Audit checks The Local Audit runs inside your WordPress admin. Nothing leaves your site, and there is no account, setup or credit card. Plugins, database, server environment and assets, scanned in one pass Mobile and desktop scores, measured separately Estimated visitor loss, with the research behind it published publicly Health Score out of 100, tracked audit over audit Plugin Audit flagging inactive, outdated and abandoned plugins Database Overview: table sizes, row counts, autoloaded options, transients and bloat Post type analysis including orphaned metadata and orphaned post records WooCommerce checks: checkout timing, cart fragments, oversized images, stuck jobs Environment checks with pass and fail states JSON export of every result Unlimited sites AI Audit, optional and account-based The AI Audit runs on the BoltAudit cloud service. It ranks findings by estimated visitors recovered and attaches the evidence behind each one. This feature sends diagnostic data from your site to a third-party service that we operate. Nothing is transmitted until you connect an account and start an audit, and the exact payload is shown to you first. See External services below. Every plan reloads AI credits weekly, including the free one. Works alongside your cache plugin BoltAudit detects WP Rocket, LiteSpeed Cache, W3 Total Cache, WP Super Cache, WP Fastest Cache and Autoptimize, and accounts for what you already have. Where the numbers come from Every visitor-loss figure is an estimate, derived from published abandonment research mapped against your measured load times, and labelled as one everywhere it appears. BoltAudit never reads your analytics. When the engine cannot produce a defensible number it says estimate unavailable rather than inventing one. When a firewall blocks a measurement, it names the blocked check and lowers the report confidence. Privacy and safety Read only. No audit modifies your site, your files or your database. Local audits stay local. Nothing leaves your site unless you run a cloud audit. You see the payload first. The exact list of what will be transmitted is shown before the first AI Audit. No frontend overhead. Audits run on demand in the admin. Nothing loads on your public site. Plans The Local Audit is free, on unlimited sites, with no time limit. Paid plans add more weekly AI credits, scheduled audits and multi-site switching. See boltaudit.com/pricing Roadmap An SEO and AEO visibility audit is in development and is not part of this release.

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.
