ODR Image Optimizer
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.
Features
- Priority Service: Injects
fetchpriority="high"and<link rel="preload">tags to bypass LCP discovery delay. - WebP Conversion: Automatically converts and serves images in next-gen formats.
- Kill Bloat: Toggle to remove heavy WordPress core scripts like the Interactivity API and Emojis.
- SOLID Architecture: Developer-friendly, strictly typed, and built for speed.
- Unified Dashboard: Manage all performance settings from a single, secure interface.
- Zero Configuration: Works out-of-the-box with sensible defaults optimized for Lighthouse 100/100.
