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 smaller 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 to 35% while keeping the visuals intact.
Google's web performance guide walks through the exact tools and techniques that made the difference.
What changed everything was automating it. 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.
Visitors never see the work, they just feel a site that loads fast, and that speed is part of why pages both convert and rank. Our Florida Local Search Index keeps showing page speed separating the businesses that rank from the ones that don't, and oversized images are the most common culprit.
Run your current images through TinyPNG or Squoosh to batch-compress them, then export two or three as WebP and compare the file size to your originals. The drop is usually dramatic, and on mobile it's the difference between a fast site and a slow one.
