<p>Built by a <a href="https://www.daviddegner.com" rel="nofollow ugc">Boston photographer</a> for site owners who care about visual quality and full control. This plugin prioritizes <strong>image quality</strong> over everything else — no subscriptions, no external services.</p>
<h3>Features</h3>
<ul>
<li><strong>Local Processing</strong> — All conversion happens on your server. No subscriptions or external API calls. Works great on a shared CPU with 2GB RAM.</li>
<li><strong>Quality First</strong> — Uses LANCZOS resizing, preserves ICC color profiles, and keeps EXIF/XMP/IPTC metadata intact.</li>
<li><strong>Fully Tunable</strong> — Control quality (0–100), speed (0–10), chroma subsampling (4:2:0, 4:2:2, 4:4:4), and bit depth (8/10/12-bit).</li>
<li><strong>Smart Fallback</strong> — Serves AVIF to supported browsers, JPEG to everyone else via picture elements.</li>
<li><strong>Automatic Conversion</strong> — Convert on upload or via daily scheduled background scans.</li>
<li><strong>LQIP Placeholders</strong> — Generate ThumbHash-based low-quality image placeholders for smooth loading.</li>
</ul>
<h3>How It Works</h3>
<p><strong>Front end:</strong> The plugin wraps your img tags in picture elements with an AVIF source. Browsers that support AVIF load the smaller, higher-quality file — others gracefully fall back to JPEG.</p>
<p><strong>Conversion:</strong> Uses ImageMagick CLI (fastest), Imagick PHP extension (high quality), or GD Library (fallback) to convert JPEGs to AVIF on upload or via background jobs.</p>
<p><strong>LQIP:</strong> Generates compact (~30 byte) ThumbHash placeholders that display instantly while images load.</p>
<h3>Server Setup</h3>
<p>The plugin supports three conversion engines, in order of preference:</p>
<h4>ImageMagick CLI (Fastest, Recommended)</h4>
<p>Uses the ImageMagick command-line binary directly:</p>
<ul>
<li><strong>System binary:</strong> ImageMagick 7.x built with HEIF/AVIF support (via libheif)</li>
<li><strong>No PHP extension required</strong></li>
<li><strong>Benefits:</strong> Fastest performance, LANCZOS resizing, full metadata preservation (EXIF, XMP, IPTC, ICC)</li>
<li><strong>Typical paths:</strong> <code>/usr/bin/magick</code>, <code>/usr/local/bin/magick</code>, or Homebrew on macOS</li>
</ul>
<p>To verify AVIF support:</p>
<pre><code>magick -list format | grep -i avif
</code></pre>
<h4>Imagick PHP Extension (High Quality)</h4>
<p>Uses the PHP Imagick extension:</p>
<ul>
<li><strong>PHP extension:</strong> imagick</li>
<li><strong>System libraries:</strong> ImageMagick built with HEIF/AVIF support (via libheif)</li>
<li><strong>Benefits:</strong> LANCZOS resizing, full metadata preservation (EXIF, XMP, IPTC, ICC), color profile handling</li>
</ul>
<p>To install on Ubuntu/Debian:</p>
<pre><code>apt install php-imagick imagemagick libheif-dev
</code></pre>
<h4>GD Library (Fallback)</h4>
<p>Uses PHP’s built-in GD library:</p>
<ul>
<li><strong>PHP extension:</strong> gd built with AVIF support (provides imageavif on PHP 8.1+)</li>
<li><strong>Note:</strong> Some distro builds omit AVIF support; limited metadata preservation</li>
</ul>
<h4>MIME Type Configuration</h4>
<p>Ensure your web server is configured to serve .avif files as image/avif.</p>

AVIF Local Support

High-quality AVIF image conversion for WordPress — local, quality-first.

<p><strong>Easy Optimizer</strong> is a free, all-in-one WordPress speed optimization plugin that can take the place of the 3–5 separate speed plugins most sites run today. One cache plugin. One dashboard. No premium upsells for core features. Prefer to keep your current cache plugin? You can also turn off the modules that overlap and use just the tools you want (see the FAQ).</p>
<p>Every toggle maps to a specific Google Lighthouse recommendation — enable it, save, and your Core Web Vitals (LCP, CLS, INP) improve immediately. Features you don’t enable never touch your page load.</p>
<h4>Core Features</h4>
<ul>
<li><strong>Full Page Caching:</strong> Achieve sub-millisecond TTFB with static HTML generation and separate mobile/desktop caches. Includes automatic sitemap-based preloading.</li>
<li><strong>Remove Unused CSS:</strong> Automatically strips unnecessary styles, generating a slim, per-page-type stylesheet to eliminate render-blocking resources.</li>
<li><strong>Delay & Defer JavaScript:</strong> Improve INP and reduce total blocking time by delaying script execution until user interaction, or deferring them natively.</li>
<li><strong>Smart Lazy Loading:</strong> Defers offscreen images, iframes, videos, and background images. Automatically adds missing width/height attributes to fix layout shifts.</li>
<li><strong>Automatic LCP Preload:</strong> Detects and preloads your Largest Contentful Paint image dynamically for instant visual loading.</li>
<li><strong>Prefetch Pages:</strong> Pre-fetches links as users hover over them, making your site feel like an instant single-page application.</li>
<li><strong>Font Optimization:</strong> Injects font-display: swap automatically to ensure text remains visible during webfont loads.</li>
<li><strong>Bloat Removal:</strong> 15 one-click toggles to safely remove unused WordPress core scripts and features.</li>
<li><strong>Database Cleanup & Optimization:</strong> Schedule automatic cleanups of revisions, auto-drafts, trashed posts, spam, and transients — each with a pre-cleanup snapshot so you can restore safely. The built-in Autoload Health auditor finds the heaviest options loaded on every page and lets you switch off the ones you don’t need, directly resolving the WordPress Site Health warning “Autoloaded options could affect performance.”</li>
<li><strong>Heartbeat & Cron Manager:</strong> Take control of server resources by limiting WordPress Heartbeat frequency and throttling WP-Cron execution directly from the dashboard (no <code>wp-config.php</code> edits required). View, run, or delete scheduled cron events.</li>
<li><strong>Cloudflare Integration:</strong> Automatically purge your Cloudflare edge cache (tag-based or full zone) whenever the page cache clears. Test your API connection instantly without saving credentials first.</li>
<li><strong>Hosting Integrations:</strong> Auto-detects your environment to automatically purge server-level cache on managed hosts including Kinsta, WP Engine, SiteGround, Cloudways, GridPane, RunCloud, SpinupWP, Rocket.net, and WordPress.com.</li>
<li><strong>Accessibility & SEO Fixes:</strong> Automatically resolves common Lighthouse accessibility warnings in real-time, such as missing form labels, ARIA tags, and un-crawlable links.</li>
<li><strong>PageSpeed Speed Test:</strong> Run a Google PageSpeed test right from your dashboard and see your score with and without Easy Optimizer, side by side, for both mobile and desktop. Includes Core Web Vitals (LCP, CLS, INP). Works out of the box with no setup, or add your own free Google API key for unlimited tests.</li>
<li><strong>Backend Analyzer:</strong> Find what slows your site down behind the scenes. Profile any page (or your admin area) on demand to see which plugins, themes, and database queries take the most time. Basically, find slow plugins and themes. Nothing runs on your real visitors, so there is no added overhead.</li>

<li>ShortPixel CDN — when Image CDN is on, your image URLs are rewritten to ShortPixel for WebP/AVIF delivery. Only image URLs are sent. <a href="https://shortpixel.com/tos" rel="nofollow ugc">Terms</a> · <a href="https://shortpixel.com/privacy" rel="nofollow ugc">Privacy</a></li>
<li>Cloudflare API — when Cloudflare is connected, your edge cache is purged (by URL or full zone) as the page cache clears. Only the URLs to purge and your zone ID are sent. <a href="https://www.cloudflare.com/website-terms/" rel="nofollow ugc">Terms</a> · <a href="https://www.cloudflare.com/privacypolicy/" rel="nofollow ugc">Privacy</a></li>
<li>Google PageSpeed Insights — when you run a speed test with your own API key, your site’s public home URL is sent to Google. <a href="https://developers.google.com/terms" rel="nofollow ugc">Terms</a> · <a href="https://policies.google.com/privacy" rel="nofollow ugc">Privacy</a></li>
<li>FluxPress PageSpeed proxy — the default speed-test path; your site registers once, then its public home URL is tested via Google so no API key is needed. <a href="https://fluxpress.io/privacy" rel="nofollow ugc">Terms & Privacy</a></li>
<li><a href="https://fluxpress.io/" rel="nofollow ugc">FluxPress</a> usage analytics — opt-in, off by default; sends anonymous data (plugin/WordPress/PHP versions, theme, locale, host, multisite/WooCommerce flags, site URL).
