This is a third-party plugin developed by Web Wonderland. 
It is not affiliated with or endorsed by WordPress, Elementor or WPBakery.
<h3>Local vs Cloud processing</h3>
The optimiser can work in two ways:
Local processing (always available) 
Runs entirely on your own server.
<ul>
<li>Unlimited WebP and AVIF generation (subject to your servers capabilities)</li>
<li>No monthly conversion caps</li>
<li>No api key required</li>
<li>Uses your own CPU and disk I/O</li>
</ul>
Cloud/API processing (api key required) 
Offloads heavy image work to the Web Wonderland Image API.
<ul>
<li>Uses a remote worker to generate WebP/AVIF for originals and all sizes</li>
<li>Reduces CPU load on your hosting, useful for busy or shared servers</li>
<li>Quotas and limits depend on your Lite, Pro or Unlimited plan</li>
<li>Works alongside local mode you can always fall back to local processing</li>
</ul>
You can choose your preferred processing mode in SEO Image Optimiser – Settings.
<h3>Free (Lite API Key)</h3>
The Lite API Key requires no card, only an email to issue an API key.
Included in the Lite API Key plan:
<ul>
<li>Unlimited local image conversions (WebP/AVIF) on your own server</li>
<li>Up to 50 cloud/API image conversions per month (WebP + AVIF) via the Web Wonderland Image API</li>
<li>Front-end WebP & AVIF delivery if available</li>
<li>Up to 30 AI alt tag & title generations per month</li>
<li>Automatic backups of originals with one-click restore</li>
<li>Works on one WordPress site</li>
</ul>
Your previously converted images remain on your server regardless of the API Key status. 
If your monthly cloud API quota is reached, the plugin can still optimise images locally.

</ul>

<h3>AI & Privacy</h3>
AI captioning is optional. If enabled, SmartAlt uses external services as documented in the External services section below. The plugin does not send personal data about site visitors.
<h3>External services</h3>
This plugin can connect to external services operated by Web Wonderland to provide optional “cloud” features (remote image optimisation and AI-powered SmartAlt captions). Local-only optimisation features continue to work without any external service.
When any cloud feature is enabled/used, the plugin sends requests from your WordPress server (admin-side actions) to the endpoints below. The plugin does not send personal data about site visitors.

WebPressor is the fastest and most powerful WordPress image optimizer plugin for converting your existing JPEG and PNG media to next-generation WebP and AVIF formats — the two formats recommended by Google for achieving perfect Core Web Vitals and PageSpeed Insights scores.
WebP images are typically 25–35% smaller than JPEG at the same quality. AVIF goes even further — delivering files up to 50% smaller than JPEG and 20% smaller than WebP. By serving these formats automatically to supported browsers, your site loads dramatically faster with zero manual effort.
Version 2.0.0 is a major release introducing AVIF support, a redesigned dashboard, live optimization logs, server-level rewrite rules, system diagnostics, and much more.
<h3>🚀 Why Image Optimization Matters</h3>
Google’s Core Web Vitals (LCP, FID, CLS) are directly impacted by image delivery performance. Large, unoptimized images are the #1 cause of slow page loads and poor PageSpeed Insights scores. WebPressor solves this automatically by:
<ul>
<li>Replacing heavy JPEG/PNG files with lightweight next-gen formats</li>
<li>Serving the smallest possible format each browser supports</li>
<li>Reducing total page weight by up to 50% with zero quality loss</li>
<li>Helping your site pass Google’s “Serve images in next-gen formats” audit</li>
</ul>
<h3>✨ Core Features</h3>
🔹 WebP Conversion — Automatically convert all JPEG and PNG images to WebP format with GD library 
🔹 AVIF Conversion (New in 2.0) — Generate AVIF images for the smallest possible file sizes (PHP 8.1+ with GD AVIF support required) 
🔹 Bulk Optimizer — Process your entire Media Library in batches with a real-time live console log 
🔹 Auto-Convert on Upload — Instantly convert new images as they are added to the Media Library 
🔹 Smart Browser Detection — Serve AVIF to AVIF-capable browsers, WebP to WebP browsers, and original images to legacy browsers 
🔹 Two Delivery Methods — Choose between HTML URL replacement or server-level <code>.htaccess</code> rewrite rules 
🔹 Adjustable Quality Sliders — Independent WebP quality (0–100) and AVIF quality (0–100) controls 
🔹 Lossy & Lossless Modes — Select compression mode for each format 
🔹 Storage Savings Dashboard — See exactly how many megabytes and what percentage you have saved 
🔹 System Status Panel — Checks GD extension, WebP/AVIF availability, folder write permissions, and server type 
🔹 Nginx Configuration Helper — Displays a copyable Nginx server block for manual rewrite rule setup 
🔹 Non-Destructive — Your original JPEG/PNG images are always preserved and never overwritten 
🔹 Compatible With All Themes — Works with Elementor, Divi, Avada, GeneratePress, Astra, Kadence, OceanWP, and more 
🔹 WooCommerce Ready — Optimizes product images, gallery thumbnails, and all image sizes automatically 
🔹 Multisite Compatible — Works on WordPress Multisite installations 
🔹 Translation Ready — Fully localized with <code>.pot</code> file included
<h3>📊 Performance Impact</h3>
 Format 
 Savings vs JPEG 
 Browser Support
 WebP 
 25–35% smaller 
 97%+ of browsers
 AVIF 
 40–50% smaller 
 80%+ of modern browsers
<h3>🛠️ How It Works</h3>
<ol>
<li>Install & activate WebPressor from the WordPress dashboard</li>
<li>Go to the WebPressor → Dashboard in the admin menu</li>
<li>Click Start Optimization to bulk-convert your existing Media Library</li>
<li>Watch the live console log as images are processed in real-time</li>
<li>Monitor your Storage Saved — the dashboard shows total bytes and percentage saved</li>
<li>New uploads are automatically converted in the background (if enabled in Settings)</li>
</ol>
<h3>⚙️ Delivery Methods</h3>
HTML Alteration (Default): 
WebPressor replaces image <code>src</code> URLs in page HTML on-the-fly. Safe, requires no server configuration, and works on any shared hosting.
Server Rewrite Rules (.htaccess): 
For Apache and LiteSpeed servers, WebPressor writes redirect rules directly into <code>/wp-content/uploads/.htaccess</code>. Requests for <code>.jpg</code> and <code>.png</code> files are transparently redirected to their <code>.webp</code> or <code>.avif</code> equivalents — this also handles background CSS images, slider images, and images loaded via JavaScript.
