Your images might be killing your LCP score. Here's why: unoptimized images delay the Largest Contentful Paint, tanking your Core Web Vitals and SEO rankings.
The fix? Smart image optimization for web. Before diving into lazy-loading and next-gen formats, compress ruthlessly. Most devs waste 60-80% of image file size unnecessarily.
Three quick wins:
1. Optimize images without losing quality — Modern compressors (like WebP) cut file sizes by 30-50% while keeping visuals sharp. Your users won't notice the difference.
2. Automate it — Manual optimization kills productivity. Automatic image optimization in your build pipeline means every image gets optimized before deployment.
3. Test your LCP — Use PageSpeed Insights. If an image is your LCP element, that's your bottleneck. Prioritize optimizing it.
Image optimization best practices? Start here: measure, compress, format-switch, cache aggressively. Done right, you'll shave 1-2 seconds off page load time alone.

The order matters here too. A lot of sites jump straight to lazy loading while they are still serving images much larger than they need. Resizing first and then compressing usually gets you most of the easy win. Olivez Image Compressor is a simple option for that one off cleanup before upload.
