Compress and Optimize WebP Images
Medium Impact+8 points estimated
Why It Matters
Images are using 116KB of unnecessary bandwidth despite already being in WebP format.
How to Fix
Increase WebP compression quality settings to reduce file sizes by 30-60% while maintaining visual quality. Use tools like Squoosh or ImageOptim to find optimal compression levels. Implement responsive images with srcset to serve appropriately sized images for different screen sizes.

AI Performance Analysis
This website has poor performance with a score of 51/100, indicating significant user experience issues. The biggest problem is render-blocking CSS files, particularly a large 127KB Tailwind CSS file that's delaying page rendering by 1.8 seconds and preventing users from seeing content quickly. The site also suffers from excessive main-thread work (34.2 seconds) that's making the page unresponsive, with users having to wait over 18 seconds before they can interact with the site. To improve performance, the site should defer or inline critical CSS, reduce the Tailwind CSS bundle size by removing unused styles, and optimize the JavaScript execution to reduce blocking time.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+25 points estimatedWhy It Matters:
CSS files are blocking initial render and delaying LCP by 1.75 seconds.
How to Fix:
Inline critical CSS directly in the HTML head for above-the-fold content. Load non-critical CSS files like card-animations.css using media='print' onload='this.media="all"' to defer them. Replace the 127KB Tailwind CDN with a custom build containing only used classes to reduce size by 75%.
Optimize Main Thread Processing
High Impact+20 points estimatedWhy It Matters:
Excessive main thread work (34.2s) creates a Total Blocking Time of 3.25 seconds, severely impacting interactivity.
How to Fix:
Break up long-running JavaScript tasks by using setTimeout() or requestIdleCallback() for non-critical operations. Minimize DOM manipulations and batch style changes together. Move heavy computations to Web Workers where possible to keep the main thread responsive.

Reduce Unused JavaScript Payload
330 KiB of unused JavaScript delays LCP by 400ms and blocks the main thread for 2 seconds.
Optimize Font Loading Strategy
Font loading delays are causing 650ms delay to First Contentful Paint and creating invisible text periods.
Add Image Dimensions Attributes
