My Images Looked Sharp.My Site Speed Tanked.
I launched a portfolio site with beautiful high-res photography. Everything looked crisp in Photoshop. Then I checked Core Web Vitals and realized I was serving 8MB image files to mobile users. The site felt sluggish, and I was losing visitors before they even scrolled.
The fix wasn't about making images smaller in dimensions, it was about reducing file size without losing quality. I started using modern formats like WebP instead of JPEG, which cut file sizes by 25-35% while keeping visual quality intact. Google's web performance guide walks through the exact tools and techniques that made the difference for me.
What changed everything was automating this process. Instead of manually compressing each image, I set up image optimization in our web design workflow so every image gets processed before it hits the server. Now I ship faster sites without sacrificing how they look.
Worth trying: Use TinyPNG or Squoosh to batch compress your current images, then export 2-3 of them as WebP to compare file size against your original format. You'll see the difference immediately.
