How to Fix Unoptimised Images
Oversized or unencoded images slowing your pages and burning LCP.
Symptoms you'll see
Serving full-resolution JPEGs/PNGs without compression, modern formats, or responsive sizing is the single biggest cause of slow pages and poor LCP.
Why it happens
Heavy images dominate page weight, wreck LCP and INP on mobile, and waste bandwidth — directly hurting rankings and conversions.
Step-by-step fix
Convert to WebP/AVIF, compress lossy, set width/height attributes, lazy-load below-the-fold images, and serve responsive srcset sizes. Use a CDN or image optimizer.
