OmegaPix Image Optimizer makes your WordPress images lighter — automatically, and entirely on your own server. When an image is uploaded it’s resized if oversized and converted to next‑gen WebP (or AVIF where your server supports it). No image is ever sent to an external service. No account, no API credits, no monthly quota.
It’s the WordPress companion to <a href="https://omegapix.app" rel="nofollow ugc">OmegaPix</a>, the privacy‑first image & PDF toolkit. Same promise, both places: your files never leave your own infrastructure.
<h4>Why OmegaPix Image Optimizer</h4>
<ul>
<li>Local‑first & private — everything runs on your server. Unlike cloud optimizers, your media is never uploaded to a third party. GDPR‑friendly by design.</li>
<li>Automatic at upload — set it once; every new upload is resized and converted. Editors don’t change how they work.</li>
<li>Accept, don’t block — large images are optimized, never rejected. Only disallowed file types are refused.</li>
<li>WebP & AVIF, best‑available — prefers AVIF, falls back to WebP, and skips gracefully if the server can’t do either.</li>
<li>You can actually see it working — a Media Library column shows each image’s status, file‑size savings, and links to the generated next‑gen files. No black box.</li>
<li>Bulk optimize your existing library — batched, time‑out‑safe AJAX runs with live progress.</li>
<li>Reprocess any single image — one click on any attachment.</li>
<li>Capability‑aware — detects GD/Imagick support for WebP/AVIF and warns you honestly instead of failing silently.</li>
<li>Safe by default — never destructive. “Replace Original” is optional, off by default, and clearly flagged Beta until rollback exists.</li>
<li>Free. The whole thing. A premium tier may come later, but the core optimizer is free.</li>
</ul>
<h4>How it helps your site</h4>
Lighter images mean faster loads, better Core Web Vitals (LCP/CLS), higher PageSpeed scores, and better SEO — without sending a single file off your server.

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.
<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>
