Optimize Logo Image Sizing
Medium Impact+8 points estimated
Why It Matters
The navigation logo is 81KB but displays at only 56x56 pixels, wasting bandwidth and delaying LCP by 350ms.
How to Fix
Resize the logo image from 2362x2362 to the actual display size of 56x56 pixels using an image editor. Convert to WebP format for better compression. Generate multiple sizes for different device pixel ratios using responsive images with srcset attribute.

AI Performance Analysis
This website has poor performance with a score of 60/100, indicating significant room for improvement. The biggest problem is excessive unused JavaScript, which is wasting 233 KB of data and slowing down page loading by over a second - this is the primary culprit behind the very slow 7.3-second Largest Contentful Paint and 4.5-second First Contentful Paint times. The site is also suffering from render-blocking CSS that could save another 160ms if optimized, and images that are unnecessarily large for their display size. Removing or deferring unused JavaScript code and properly sizing images would likely improve the performance score by 15-20 points and dramatically enhance the user experience.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+25 points estimatedWhy It Matters:
233 KiB of unused JavaScript is delaying LCP by 1.35 seconds and blocking user interactions.
How to Fix:
Analyze your bundled JavaScript to identify unused code using webpack-bundle-analyzer. Implement code splitting to load only necessary components initially. Remove or defer Google Analytics and other tracking scripts until after page load. Consider tree-shaking to eliminate dead code from your build process.
Inline Critical CSS
Medium Impact+7 points estimatedWhy It Matters:
Render-blocking CSS is delaying First Contentful Paint by 160ms and preventing faster page rendering.
How to Fix:
Extract above-the-fold CSS styles and inline them directly in the HTML head. Use tools like Critical or Critters to automatically identify critical CSS. Load the remaining CSS asynchronously using media='print' onload technique or preload with rel='preload'.
