<h4>Key Features</h4>
<ul>
<li>Instant Preview – Server-generated WebP preview images display immediately</li>

<li>Gutenberg Block – Native block editor integration</li>
<li>Shortcode Support – Works in classic editor and widgets</li>
<li>Keyboard Navigation – Full keyboard and screen reader accessibility</li>
<li>Mobile Optimized – Touch gestures for page navigation and zoom</li>
</ul>
<h4>Performance</h4>

<li>Initial page load: < 10KB JavaScript</li>
<li>First paint: < 200ms</li>
<li>Full viewer: Loads on-demand</li>
<li>Preview images: Optimized WebP format</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>Upload a PDF to your media library</li>

<li>Visitors see an instant preview image</li>

</ol>
<h4>Requirements</h4>

<li>ImageMagick with PDF support (recommended)</li>
<li>Ghostscript</li>
</ul>
<p>The plugin will detect available options and use the best method automatically.</p>
<h4>Shortcode Usage</h4>

<li>load – When to load viewer: click, visible, immediate (default: click)</li>

</ul>
<h3>Privacy</h3>

<li>Does not collect any personal data</li>
