<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>
