Why Convert to WebP
Faster Websites
WebP images are 25–35% smaller than PNGs, reducing page load times significantly and improving Core Web Vitals.

Google rewards faster sites with higher rankings. WebP is a recommended next-gen format for Lighthouse and Core Web Vitals.
Privacy Friendly

SEO & Performance Benefits
Google Lighthouse Scores
WebP helps you pass Google Lighthouse audits for "Serve images in next-gen formats". This directly boosts your performance score, contributing to better search rankings and user experience across desktop and mobile.
Core Web Vitals
Smaller image files improve Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS). WebP's superior compression means faster loading hero images, which directly impacts your Core Web Vitals assessment and user retention.
Bandwidth Savings
WebP reduces image file sizes by 25–35% compared to PNG with no perceptible quality loss. For sites with many images, this translates to significant bandwidth savings, lower hosting costs, and faster page loads for visitors on slow connections.
