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.

OmegaPix Image Optimizer – Convert WebP & AVIF (Local, No Cloud)

Optimize images and convert to WebP & AVIF on your own server. Local, private, no cloud, no credits — faster site and better Core Web Vitals.
