Why It Matters
Large unoptimized images delay LCP by 6.6 seconds and consume 5.6MB of unnecessary bandwidth.
How to Fix
In Webflow Designer, reupload the hero background (2.9MB PNG) and mascot GIF as optimized WebP/MP4 formats. Use Webflow's responsive image settings to serve appropriately sized images. Replace the meditation GIF with a compressed MP4 video for 70% smaller file size.

AI Performance Analysis
This Webflow site has poor performance with a score of 42/100 and critical Core Web Vitals issues. The biggest problem is extremely slow image loading, with your Largest Contentful Paint taking 10.7 seconds - nearly 7 seconds slower than Google's recommended threshold. Your site is loading over 5.6MB of unoptimized images, including large PNG files that should be converted to modern formats like WebP, and oversized images that need proper compression. Additionally, there's significant JavaScript blocking (2.8 seconds of execution time) and 31KB of unused CSS slowing down your initial page render, resulting in a painful 16+ second Time to Interactive that will frustrate users and hurt search rankings.
Other Optimization Recommendations
Remove Unused CSS Rules
High Impact+15 points estimatedWhy It Matters:
85% of your main stylesheet (31KB) is unused, blocking render and delaying first paint by 150ms.
How to Fix:
Use Webflow's built-in CSS optimization by removing unused classes and interactions in the Designer. Audit your style manager for orphaned styles. Consider splitting critical above-the-fold styles into a separate inline block in your page settings.
Add Image Dimensions Attributes
Medium Impact+8 points estimatedWhy It Matters:
Images without explicit dimensions cause layout shifts when they load, degrading user experience.
How to Fix:
In Webflow Designer, select each image element and set fixed width/height values in the Style panel. For the hero images, add aspect-ratio CSS property via custom code. Use Webflow's responsive settings to maintain proper scaling across breakpoints.
