Why It Matters
Your logo image can be reduced by 84% using modern formats, improving perceived performance.
How to Fix
Configure your imgproxy service to automatically serve WebP or AVIF formats for supported browsers. Increase compression settings for the logo since it's small and decorative. Add proper srcset attributes for responsive delivery based on device capabilities.

AI Performance Analysis
This website has good performance with a score of 83/100, but there's still room for improvement. The biggest issue is excessive unused CSS, which is wasting 54 KB of data and could save 450ms in load time - nearly 92% of the CSS file isn't being used on this page. The site also suffers from forced reflows caused by JavaScript that's measuring page elements inefficiently, and the Largest Contentful Paint takes 3.9 seconds, which is slower than ideal. Removing unused CSS and optimizing the JavaScript that causes layout thrashing would provide the most significant performance gains.
Other Optimization Recommendations
Remove Unused CSS Rules
High Impact+8 points estimatedWhy It Matters:
91% of your CSS is unused, wasting 54 KiB and delaying LCP by 450ms.
How to Fix:
Use PurgeCSS or UnCSS to remove unused styles from your stylesheet. Split critical above-the-fold CSS into a separate file and inline it. Defer loading of non-critical CSS using media='print' onload trick or loadCSS library.
Eliminate Forced Reflow Issues
High Impact+6 points estimatedWhy It Matters:
JavaScript is triggering 100ms+ of forced reflows, blocking user interactions and degrading performance.
How to Fix:
Batch DOM reads and writes to avoid layout thrashing. Cache geometric properties like offsetWidth instead of repeatedly querying them. Move DOM measurements outside of Alpine.js reactive functions or use requestAnimationFrame for layout-heavy operations.
