MITS Image Optimizer 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.
<h4>Features</h4>
Auto-Compress on Upload 
Every JPG/PNG above a configurable size threshold is automatically scaled and compressed before WordPress generates its thumbnail sizes. No extra steps needed.
Bulk Compression 
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.
WebP Converter 
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.
AVIF Converter 
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.
Apache .htaccess Configuration 
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.
Image Dimensions Scanner 
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.
Site Audit 
Scans your site for the most common technical issues: missing alt text, oversized images, missing SSL, outdated plugins, pages without Open Graph tags, and more.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.
Dashboard Widget 
A compact stats panel on the WordPress admin dashboard showing compression savings, WebP/AVIF conversion counts, and a link to the optimizer.
