<p>Anek Image Optimizer is a professional-grade image optimization plugin built for speed, privacy, and flexibility. It is 100% free, runs entirely on your own server, and ships with zero telemetry — your images never leave your infrastructure.</p>
<h4>Multi-Library Engine</h4>
<p>Most optimization plugins lock you into a single backend. Anek supports three simultaneously:</p>
<ul>
<li><strong>Libvips</strong> — the fastest image processing library available (the same engine used by Cloudinary and Sharp.js). Runs as a native binary for extreme throughput and minimal memory usage.</li>
<li><strong>Spatie Image</strong> — PHP-native library with selectable GD or Imagick drivers.</li>
<li><strong>Intervention Image</strong> — alternative PHP library with GD or Imagick drivers.</li>
</ul>
<h4>Next-Gen Format Output</h4>
<ul>
<li>Compress original <strong>JPEG and PNG</strong> files in-place.</li>
<li>Generate <strong>WebP</strong> sidecar files alongside originals.</li>
<li>Generate <strong>AVIF</strong> sidecar files alongside originals.</li>
<li>All three outputs from a single source image, in one operation.</li>
<li>Built-in Apache/LiteSpeed <code>.htaccess</code> rules and Nginx config snippets for zero-PHP server-level delivery — browsers that support AVIF or WebP get them automatically; others fall back gracefully.</li>
</ul>
<h4>Deep WordPress Integration</h4>
<ul>
<li>Optimize directly from the <strong>Media Library</strong> — per-image buttons appear in attachment details.</li>
<li><strong>Bulk optimization</strong> — compress your entire media library in one click with real-time progress.</li>
<li><strong>Auto-optimize on upload</strong> — new images are processed the moment they are added.</li>
<li><strong>File-system deep scanner</strong> — discovers and optimizes images outside <code>wp-content/uploads</code>, including theme images, plugin assets, and custom directories.</li>
</ul>
<h4>Preserve Originals</h4>
<p>Toggle on “Preserve Originals” and a backup copy of every image is kept before compression. Restore any image to its original state at any time with zero data loss.</p>
<h4>Quality & Exclusion Controls</h4>
<ul>
<li>Adjustable quality slider (0–100) per compression run.</li>
<li>Strip EXIF metadata to reduce file size further.</li>
<li>Set a minimum file size threshold to skip images already small enough.</li>
<li>Exclude specific paths from bulk operations.</li>
</ul>
<h4>100% Free, Zero Telemetry, Fully Self-Hosted</h4>
<ul>
<li><strong>No data leaves your server.</strong> All processing happens locally.</li>
<li><strong>Zero telemetry</strong> — no usage tracking, no analytics, no phone-home requests.</li>
<li><strong>No API keys, no accounts, no subscriptions.</strong></li>
<li>Full feature set available from day one with no freemium locks or upsells.</li>
</ul>
