<p><strong>MITS Image Optimizer</strong> is a professional image optimization toolkit for WordPress. It compresses images automatically on upload, batch-converts your entire media library to WebP and AVIF, configures Apache to serve next-gen formats automatically, and scans your site for common technical SEO issues.</p>
<h4>Features</h4>
<p><strong>Auto-Compress on Upload</strong><br />
Every JPG/PNG above a configurable size threshold is automatically scaled and compressed before WordPress generates its thumbnail sizes. No extra steps needed.</p>
<p><strong>Bulk Compression</strong><br />
Run a background batch job to compress all existing images in your media library. Progress is tracked and the job runs asynchronously – it won’t block your browser.</p>
<p><strong>WebP Converter</strong><br />
Batch-convert all JPG/PNG/GIF files in your uploads directory to WebP format. Runs in the background using WP-Cron or a loopback HTTP request. Supports both Imagick and GD libraries.</p>
<p><strong>AVIF Converter</strong><br />
Convert images to AVIF – the next-generation format that can be 30–50% smaller than WebP. Requires Imagick 7+ with AVIF support or PHP 8.1+ with GD <code>imageavif()</code>. The plugin detects support automatically and warns you if AVIF is unavailable on your server.</p>
<p><strong>Apache .htaccess Configuration</strong><br />
One click adds <code>mod_rewrite</code> rules to your <code>.htaccess</code> so Apache automatically serves <code>.webp</code> files to browsers that support them, with no code changes required in your theme.</p>
<p><strong>Image Dimensions Scanner</strong><br />
Detects images ≥ 1600 px wide that are used in posts or as featured images. Helps you find oversized images that slow down page loads, along with their file sizes, dimensions, and WebP/AVIF conversion status.</p>
<p><strong>Site Audit</strong><br />
Scans your site for the most common technical issues: missing alt text, oversized images, missing SSL, outdated plugins, pages without Open Graph tags, and more. Results include actionable recommendations.</p>
<p><strong>Dashboard Widget</strong><br />
A compact stats panel on the WordPress admin dashboard showing compression savings, WebP/AVIF conversion counts, and a link to the optimizer.</p>
<h4>Requirements</h4>
<ul>
<li>PHP 8.0+, WordPress 6.0+</li>
<li>GD or Imagick PHP extension (for WebP/compression)</li>
<li>Imagick 7+ with AVIF or PHP 8.1+ GD (for AVIF conversion)</li>
<li>Apache + <code>mod_rewrite</code> (for automatic WebP serving via <code>.htaccess</code>)</li>
</ul>
