Slow React App? Your Images Might Be the Problem |
Your React app might be fast…
until your images ruin it.
Unoptimized images are a major cause of slow page loads — especially on mobile.
Here’s how to fix it:
✅ Use loading="lazy" on img— defer loading until needed
✅ Use srcSet to serve responsive image sizes
✅ Convert images to WebP — smaller, faster, modern
✅ Offload large assets to a CDN
✅ Use react-lazyload for component-based image loading
✅ If using Next.js — leverage the built-in Image component for automatic optimization
Smarter image handling = Faster UX + Better Core Web Vitals
