How WebP Image Compression Boosts Core Web Vitals and SEO

Learn how modern WebP compression cuts image payloads by up to 60% without visible loss in quality, improving LCP and user retention.

Images typically account for over 50% of the total byte weight of a webpage. When browsers download massive JPEG or uncompressed PNG assets, the Largest Contentful Paint (LCP) metric skyrockets, directly degrading Google search rankings. By switching to WebP and applying client-side lossy compression, you preserve essential edge sharpness while eliminating redundant color profile headers and unneeded metadata. Try our browser-based Image Compressor tool to optimize your graphics with fast in-browser execution.
