WordPress sites accumulate heavy, unoptimized images over time. A 6000×4000 phone photo dropped straight into a post, full-resolution originals from every contributor, formats the browser has to work harder to render. The result is slow page loads, weaker Core Web Vitals, and SEO that quietly suffers. The usual fixes are either manual (so they happen inconsistently) or cloud services that upload your media to a third party, adding cost, latency, and a privacy footprint. OmegaPix Image Optimizer takes a different path: it is local-first and automatic. Every new upload is resized and converted to next-gen formats at the moment it enters the media library, using PHP GD or Imagick on your own server. It prefers AVIF, falls back to WebP, and skips gracefully when neither is available; it tells you honestly what your server can do rather than failing silently. Large images are optimized, never rejected; only disallowed file types are refused. The Media Library shows optimization state and file-size savings inline, and a timeout-safe bulk tool brings existing media up to date. OmegaPix Image Optimizer is the WordPress companion to the OmegaPix browser tools from WebX Developers. The plugin is free. No cloud, no third-party servers, no credits.
What it solves
WordPress has no built-in answer to image weight. Contributors upload straight from their phones at 6000x4000, originals land at full resolution in legacy formats, and the media library steadily turns into a performance liability. Heavy images drag down LCP and CLS, push PageSpeed scores down, and erode SEO. The common remedies each have a catch: manual resizing and conversion is tedious and inconsistent, while cloud optimizers solve the work by shipping every file off to a third-party service — adding per-image cost or credits, network latency, and a privacy and GDPR footprint you now have to account for.
What it does
OmegaPix Image Optimizer hooks into the WordPress upload pipeline and optimizes every new image the moment it arrives, resizing oversized files to a sensible maximum dimension and generating next-gen versions, all on your own server using PHP GD or Imagick. It prefers AVIF, falls back to WebP, and skips gracefully when a format is unavailable, detecting your server's real capabilities and warning you honestly rather than failing in silence. It accepts and optimizes large images instead of blocking them; only disallowed file types are refused. The Media Library gains a status column showing optimization state, file-size savings, and links to the next-gen files, and a batched, timeout-safe bulk tool brings existing media up to date with live progress. It is safe by default and non-destructive; the optional "Replace Original" mode is off by default and clearly flagged Beta. Nothing is uploaded to OmegaPix or any third party: no cloud, no third-party servers, no credits.
What's included.
Screens.
The image-weight problem, solved locally.
WordPress sites pile up heavy, unoptimized images that slow loads and drag down Core Web Vitals. OmegaPix fixes that at the point of upload — on your own server, with nothing sent anywhere.
Heavy images, slow site
A single 6000×4000 phone photo can outweigh an entire page. Multiply that across every upload and your Core Web Vitals and SEO both suffer.
Manual fixes don't stick
Resizing and converting by hand is tedious, so it happens inconsistently. The next contributor undoes your discipline with one drag-and-drop.
Cloud optimizers cost and expose
Services that fix the problem ship every file to a third party — adding credits, latency, and a privacy and GDPR footprint you have to manage.
OmegaPix stays on your server
Optimization and next-gen conversion run locally via PHP GD or Imagick, automatically at upload. No cloud, no third-party servers, no credits.
Automatic, private, and honest about what your server can do.
Automatic at upload
Every new image is resized and converted the moment it lands — no extra step, no change to how you publish.
WebP and AVIF
Prefers AVIF for the smallest files, falls back to WebP, and skips gracefully when a format isn't supported.
Local-first and private
Runs on your own server with PHP GD or Imagick. Nothing leaves the site, which keeps things GDPR-friendly.
Accept, don't block
Large images are optimized, not rejected. Only disallowed file types are refused — so no one's upload silently fails.
Visibility in the Media Library
A status column shows optimization state, file-size savings, and links straight to the next-gen versions.
Bulk and single reprocess
Bring existing media up to date with a batched, timeout-safe bulk tool, or re-optimize any one image in a click.

Common questions before you install.
Does it upload my images to the cloud?
No. All optimization runs on your own server using PHP GD or Imagick. Nothing is sent to OmegaPix or any third party. No cloud, no third-party servers, no credits.
What about AVIF and WebP support?
OmegaPix prefers AVIF for the smallest files and falls back to WebP. It detects what your server's image library actually supports and tells you honestly, skipping a format gracefully if it isn't available.
Will it reject large uploads?
No. Large images are resized and optimized rather than blocked. Only disallowed file types are refused, so a contributor's upload never silently fails because the file was big.
Can I optimize the images already in my library?
Yes. The bulk optimization tool processes existing media in timeout-safe batches with live progress, and you can re-optimize any single attachment with one click.
Is it really free?
Yes. The plugin is free, and the full optimize-and-convert workflow is not paywalled.
Will it change or delete my originals?
Not by default. OmegaPix is non-destructive out of the box. An optional "Replace Original" mode exists, but it's off by default and clearly flagged Beta.
