How Image Compression Boosts Core Web Vitals (LCP)
Uncompressed images are the leading cause of poor Largest Contentful Paint (LCP) scores in Google PageSpeed Insights. When multi-megabyte hero graphics are delivered to mobile smartphones, cellular bandwidth is saturated, delaying page interactivity and damaging search rankings.
By resampling image data through browser Canvas and leveraging modern image/webp re-encoding at 75%–80% quality, you retain crisp visual fidelity while stripping away invisible EXIF metadata and redundant color frequency blocks.
