Why Convert JPG to WebP? (Faster Page Speeds & Core Web Vitals)

WebP can reduce a JPEG photo’s file size, depending on its detail, dimensions and selected quality. Convert your image locally, compare the actual bytes and visual result, and keep the format that suits its destination.

Faster image delivery directly boosts your Core Web Vitals, reduces Largest Contentful Paint (LCP) times, and improves search engine ranking potential.
