Description
Images are the #1 performance bottleneck on WordPress websites.
Oversized uploads, unused images left in the Media Library, and unoptimized WooCommerce product images silently slow down pages, hurt Core Web Vitals, and reduce conversions.
WBN Image Optimizer is not a simple image compression plugin.
It is a professionally built, SaaS-grade image optimization system, delivered as a WordPress plugin.
Everything runs on your own server:
• No external image processing
• No third-party APIs for optimization
• No data collection or tracking
• No privacy or compliance risks
You stay in control — technically and operationally.
What This System Improves
• Faster page load times (40–60% smaller images)
• Higher Google PageSpeed & Core Web Vitals scores
• Better WooCommerce performance
• Lower bandwidth and disk usage
• A clean, maintainable Media Library
If a WordPress site feels heavy, images are usually the reason.

SaaS Architecture & Licensing
WBN Image Optimizer is built as a self-hosted SaaS system:
