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>

Image Format Converter is a powerful, lightweight administrative tool that allows you to easily convert images in your WordPress Media Library to modern formats like WebP and AVIF, as well as standard PNG and JPG formats.
By leveraging your server’s native PHP image processing libraries (GD or Imagick), this plugin converts images with high quality and optimal compression. With the newly added AJAX-powered engine, you can now select and convert multiple images at once, watch their progress in real-time with an animated progress bar, and see exactly how many kilobytes and storage percentage you saved.
Features: 
* AJAX Bulk Conversion: Select multiple images from the Media Library and convert them sequentially. Prevents script timeouts on large libraries. 
* Proportional Resizing: Set optional maximum width or height constraints to scale down high-resolution images during conversion. 
* Media Library Row Action: Convert images directly from the Media Library list view (<code>upload.php</code>) with a quick “Convert Format” link. 
* Size Savings Calculator: Shows original size, converted size, and total storage savings in real-time. 
* Metadata Control (EXIF Stripping): Clean up extra file space by stripping camera EXIF profiles and color data when using Imagick. 
* Auto-Delete Original: Clean up your server automatically by deleting the original image file and database attachment after a successful conversion. 
* Flexible settings: Configure JPEG quality, PNG compression levels, WebP/AVIF quality, and toggle Media Library registration. 
* Server Diagnostics: View library status (GD, Imagick, WebP, AVIF) at a glance, with step-by-step instructions to enable missing libraries.
