Optimize Image Sizes and Compression

High Impact+1 points estimated

Why It Matters

Oversized images waste 58KB of bandwidth with the hero image alone being 89% larger than needed for display.

How to Fix

Resize hero image from 960x505 to 665x499 pixels to match display dimensions. Create responsive image variants using srcset attribute. Compress testimonial images more aggressively - Malin Isenfors image can be reduced by 8KB through better compression.

AI Performance Analysis

This website performs very well with an excellent score of 96/100, indicating fast loading times for most users. The main issue affecting user experience is the CSS stylesheet blocking the initial page render, which delays content visibility by about 110ms and could be fixed by inlining critical styles or deferring non-essential CSS. Additionally, the site's images are larger than needed for their display size, wasting 58 KB of download data, and cache settings could be improved to speed up repeat visits. While the Largest Contentful Paint of 2.5 seconds is acceptable, addressing the render-blocking CSS and optimizing image sizes could push this site to near-perfect performance.

Other Optimization Recommendations

Eliminate Render Blocking CSS

High Impact+2 points estimated

Why It Matters:

The main stylesheet blocks initial page render for 153ms, directly delaying First Contentful Paint by 100ms.

How to Fix:

Inline critical CSS for above-the-fold content directly in the HTML head. Load the remaining CSS asynchronously using media='print' onload="this.media='all'" technique. Minify the stylesheet to reduce its 7.6KB size further.

Extend Browser Cache Lifetimes

Medium Impact+1 points estimated

Why It Matters:

Short cache durations force repeat visitors to re-download resources, slowing subsequent page loads.

How to Fix:

Set cache headers for static assets (CSS, JS, images) to 1 year instead of current 1 week. Add cache-busting query parameters (you already use ?v=ab565d2e for CSS) for version control. Configure server to set proper Cache-Control headers for all static resources.
