WebP vs. JPEG vs. PNG: Which Image Format is Best?
Choosing the right image format dramatically improves page load speeds, reduces mobile data usage, and boosts Google Search rankings:
Developed by Google. Offers 30% smaller file sizes than JPEG with identical visual quality. Supports both transparency (like PNG) and animation (like GIF).
Best for legacy camera photos. Does not support transparent backgrounds, but is supported by 100% of devices since 1992.
Lossless format ideal for logos, sharp icons, and transparent overlays. Typically produces much larger file sizes than WebP.
How Compressing Images Boosts Core Web Vitals (LCP)
Google's search ranking algorithm heavily penalizes slow-loading websites through the Largest Contentful Paint (LCP) metric. Oversized hero banners (3MB–8MB) are the #1 cause of failing LCP scores.
By converting full-resolution images into compressed WebP files under 200KB, your pages render in under 1.2 seconds, satisfying Google's strict "Good" Core Web Vitals threshold.
