Remove Unused JavaScript Polyfills
Medium Impact+0.5 points estimated
Why It Matters
Legacy JavaScript polyfills add 14KB of unnecessary code for modern browser features already supported.
How to Fix
Update your Next.js browserslist configuration to target modern browsers (Chrome 91+, Firefox 90+). Configure Babel to exclude polyfills for Array.at, Array.flat, Object.fromEntries and other baseline features. Use next.config.js with experimental.browsersListForSwc to optimize bundle for your target browsers.

AI Performance Analysis
This Next.js site has excellent performance with a score of 98/100, but there are still some quick wins available. The biggest issue is render-blocking CSS that's delaying your page's initial paint by 150ms, which could be fixed by inlining critical styles or deferring non-essential CSS. Your logo image could be optimized by converting it to WebP format and properly sizing it for its display dimensions, saving about 55KB. Additionally, removing unused JavaScript polyfills for modern browser features like Array.flat and Object.hasOwn could save another 14KB and further improve load times.
Other Optimization Recommendations
Eliminate Render-Blocking CSS
High Impact+1 point estimatedWhy It Matters:
Render-blocking CSS is delaying LCP and FCP by 150ms, preventing users from seeing content immediately.
How to Fix:
In your Next.js app, move critical CSS inline or use next/dynamic for non-critical styles. Split your CSS chunks and load non-critical styles asynchronously using media='print' onload="this.media='all'" technique. Consider extracting above-the-fold styles into a separate critical CSS bundle.
Optimize Logo Image Performance
Medium Impact+0.5 points estimatedWhy It Matters:
Your logo image wastes 56KB and lacks proper dimensions, affecting both loading speed and layout stability.
How to Fix:
Convert logo.png to WebP or AVIF format for 30-50% size reduction. Resize the image from 431x409 to match display dimensions of 177x168. Add explicit width='177' height='168' attributes to the img tag to prevent layout shifts and improve CLS.
