Fix Unoptimized Images

Unoptimized Images

  • Problem: Images are too large in file size or dimensions.
  • Why it fails: Slows down LCP and overall page load, consumes unnecessary bandwidth.
  • How to Fix "optimize images for web":
    • Compress Images: Use tools like Squoosh, TinyPNG, or imageoptim-cli. Aim for a balance between quality and file size.
    • Use Modern Formats: Serve WebP or AVIF where supported, with fallbacks (e.g., using the <picture> element).
      <picture>
        <source srcset="image.avif" type="image/avif">
        <source srcset="image.webp" type="image/webp">
        <img src="image.jpg" width="600" height="400" alt="...">
      </picture>
      
    • Serve Responsive Images: Use srcset and sizes attributes to provide different image sizes for different screen resolutions and viewport sizes.
