<p>JZB Image Auto AVIF is an image optimization engine that helps WordPress users automatically generate compressed AVIF and WebP images. It does this without altering the original media library files, utilizing an independent cache directory architecture to safely serve optimized images to browsers.</p>
<h3>Core Features:</h3>
<ul>
<li><strong>Non-destructive Cache</strong>: Generated AVIF and WebP files are stored in a separate <code>wp-content/uploads/jzb-image-auto-avif/</code> directory. Uninstalling the plugin instantly restores your original media library.</li>
<li><strong>Dual-Core Compression</strong>: Configure distinct quality settings for AVIF and WebP formats. Supports fine-grained adjustment and switching between lossy and lossless modes.</li>
<li><strong>HTML Output Buffering</strong>: Dynamically replaces image links in the front-end HTML source without relying on <code>.htaccess</code> or <code>nginx.conf</code> rewrite rules.</li>
<li><strong>Native Intervention Control</strong>: Provides toggles to prevent WordPress from generating unnecessary multi-size thumbnails or applying <code>-scaled</code> changes, helping to save server disk space.</li>
<li><strong>Media Library Controls</strong>: Includes AJAX buttons in the Media Library list view to generate AVIF/WebP for individual old images or cleanly delete legacy thumbnails.</li>
<li><strong>Dynamic Loading Thresholds</strong>: Recommends sizing configurations based on your server’s available CPU cores and RAM to prevent server timeouts during heavy image conversion.</li>
</ul>

<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>
