Why File Size Matters So Much

Image file size directly impacts website performance, email deliverability, and storage usage. Google's Core Web Vitals score penalizes slow-loading pages — and oversized images are the #1 cause of poor LCP (Largest Contentful Paint) scores. For every 100ms faster a page loads, conversion rates improve by roughly 1%. Reducing image file sizes is one of the highest-ROI optimizations you can make for any website.
