<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>LessFlux is an external image and video optimization plugin for WordPress that helps reduce media file sizes, improve delivery performance, and offload optimization workloads from your hosting environment.</p>
<p>Unlike traditional optimization plugins that process files directly on your server, LessFlux performs all optimization tasks externally. Images and videos are compressed, converted, and delivered through LessFlux infrastructure, helping reduce CPU usage, memory consumption, and long-running optimization jobs on your WordPress installation.</p>
<p>Whether you’re running a personal website, WooCommerce store, agency portfolio, membership site, or content-heavy publication, LessFlux helps streamline media optimization while keeping your WordPress environment lightweight.</p>

<li>LessFlux processes media externally and delivers optimized assets through the CDN.</li>
<li>Existing media can be optimized in bulk using background processing.</li>
<li>Bulk optimization jobs continue running even if you close your browser or leave the page.</li>
