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

<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.
