1. Understanding Largest Contentful Paint (LCP) in 2026
Largest Contentful Paint measures the render time of the largest image or text block visible within the initial viewport. Google considers an LCP under 2.5 seconds as 'Good'. On over 85% of modern websites, the LCP element is a hero graphic or product photography.
2. Real-Time Bitrate Tuning vs Visual Perceptibility
Human eyes cannot distinguish the difference between a 100% quality JPEG and an 80% quality WebP image on standard high-density mobile screens. By tuning quality to 80-85%, you can reduce payload sizes by 70% while maintaining crisp sharpness and passing Google PageSpeed audits.
