2. Better Core Web Vitals Scores

Google’s Core Web Vitals measure key metrics like:

• First Input Delay (FID) – how fast a page responds to clicks
• Cumulative Layout Shift (CLS) – how stable the page is during load

Large image formats can make LCP and FID scores slower, which can hurt your rankings. Using lighter formats can really boost these scores a lot.
