<p>Welcome to <strong>Henkan</strong> (Japanese for “conversion”) — your lightweight, high-performance solution for next-generation image optimization in WordPress!</p>
<p>Slow loading times and heavy images are a thing of the past. Henkan seamlessly integrates into your WordPress dashboard, silently converting your standard JPEGs and PNGs into highly optimized <strong>WebP</strong> or <strong>AVIF</strong> files. Boost your Core Web Vitals, improve your SEO rankings, and save massive amounts of server bandwidth without sacrificing an ounce of image quality.</p>
<h3>✨ Why choose Henkan?</h3>
<p>Most image optimizers rely on slow PHP processing or expensive cloud APIs with monthly limits. Henkan is built differently: It prioritizes <strong>native OS binaries</strong> (<code>cwebp</code>, <code>avifenc</code>) to process images blazingly fast directly on your own server, completely free and without any restrictions.</p>
<h3>🚀 Powerful Features</h3>
<ul>
<li><strong>Next-Gen Formats:</strong> Instantly convert images to WebP and AVIF formats.</li>
<li><strong>Zero-Config Auto-Conversion:</strong> New images are optimized silently in the background the moment you upload them.</li>
<li><strong>1-Click Bulk Optimization:</strong> Got a massive existing media library? Process thousands of images with a single click in our beautiful, modern dashboard.</li>
<li><strong>Smart Fallbacks:</strong> Uses ultra-fast <code>exec()</code> binaries when available, falling back to GD or ImageMagick seamlessly if needed.</li>
<li><strong>Cache Auto-Clear:</strong> Fully compatible with WP Rocket, W3 Total Cache, Autoptimize, and LiteSpeed Cache. Conversions automatically trigger a cache purge.</li>
<li><strong>Frontend Delivery:</strong> Automatically serves the optimized images to compatible browsers using modern HTML <code><picture></code> tags or Nginx/Apache rewrites.</li>
<li><strong>WP-CLI Power:</strong> Built-in commands (<code>wp henkan convert</code>) for sysadmins to process massive libraries directly from the terminal without PHP timeouts.</li>
<li><strong>Global Ready:</strong> 100% translation-ready. Shipped with English, German (<code>de_DE</code>), and Japanese (<code>ja</code>) out of the box.</li>
</ul>
<h3>🛠️ System Requirements</h3>
<p>To unleash the full speed of Henkan, we recommend:<br />
* <strong>WordPress:</strong> 6.0 or higher<br />
* <strong>PHP:</strong> 7.4 or higher<br />
* <strong>For WebP:</strong> <code>cwebp</code> installed on the server (recommended) OR PHP <code>GD</code> extension with WebP support.<br />
