  width="64"
  height="64"
>

Performance Tips

Lazy Loading

Use loading="lazy" for logos below the fold to improve initial page load.

Specify Dimensions

Always include width and height to prevent layout shift during loading.

Preload Critical Logos

For logos above the fold, use <link rel="preload">.

WebP Format

Our API returns WebP by default — 25-35% smaller than PNG with full browser support.
