ODR Image Optimizer is a professional-grade performance suite built on SOLID principles. Unlike monolithic optimization plugins, ODR focuses on the critical rendering path to eliminate resource discovery delays.
Designed to hit a 100/100 Lighthouse score on mobile under standard configurations. By decoupling image processing from delivery policy, the plugin reduces Largest Contentful Paint (LCP) by optimizing how the browser prioritizes assets.
Performance Results (reference test site, mobile Lighthouse): 
– Largest Contentful Paint (LCP): 1.4s (↓ 1.0s improvement) 
– First Contentful Paint (FCP): 1.0s 
– Total Blocking Time (TBT): 0ms 
– Cumulative Layout Shift (CLS): 0
Real-world numbers will vary based on theme, hosting, and content.
<h3>Features</h3>
