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

Perfect Images handles the basics of WordPress image management that should have been built-in from the start. Manage image sizes, disable the ones you don’t need, add custom sizes, and regenerate thumbnails in bulk. It’s the essential foundation every WordPress install needs for clean, efficient image handling.
Think of it as your image management base layer. WordPress creates too many sizes? Disable them. Need a custom thumbnail size? Add it. Want retina support or modern formats like WebP/AVIF? Enable those modules. Perfect Images gives you complete control without bloat.

<h3>Core Features</h3>
⚙️ Image Size Management 
The foundation of everything. View all registered image sizes (WordPress defaults, theme sizes, plugin sizes), disable the ones you don’t need, and add custom sizes. Finally, control over those pesky WordPress-generated sizes like <code>medium_large</code>, <code>1536x1536</code>, and <code>2048x2048</code>.
🔄 Regenerate Thumbnails 
Bulk regenerate thumbnails after changing sizes or switching themes. Progress tracking, smart processing, and automatic cleanup of old unused sizes.
🖼️ Retina Images (Module) 
Optional module for high-DPI displays. Automatically generate and serve crisp @2x versions of your thumbnails. Works seamlessly with WordPress responsive images.
🎨 Modern Formats (Module) 
Optional WebP/AVIF conversion. Convert images to modern formats for smaller file sizes and faster loading—without replacing your originals.
🚀 Easy IO (Module) 
Optional CDN-based image optimization via EWWW. Automatically converts and delivers your images in WebP/AVIF, resizes on the fly, and serves them from a global CDN—zero server configuration required.
🤖 AI Features (Module) 
Optional AI-powered tools. Upscale images via Claid.ai when your source is too small, or use the AI Assistant to analyze your sizes and recommend which to enable or disable based on your theme’s srcset needs.
