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

Your images stay on your device. No uploads, no servers, no tracking. All conversion happens client-side.

Free Forever

Unlimited conversions with no watermarks, sign-ups, or hidden charges. Always free for everyone.

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.
