Browser caching

Every logo request includes cache headers that tell browsers to store logos locally for 24 hours: 
Cache-Control: public, max-age=86400
This happens automatically per user:
  1. First visit - User’s browser downloads logo from Logo.dev CDN
  2. Repeat visits - Browser serves cached logo instantly (no API call)
  3. After 24 hours - Browser fetches fresh logo if needed
Each user caches logos on their own device. This reduces API requests and provides instant load times without any configuration.

Best practices

Preload critical logos: 
<link
  rel="preload"
  as="image"
  href="https://img.logo.dev/stripe.com?token=LOGO_DEV_PUBLISHABLE_KEY"
/>
Lazy load below the fold: 
<img
  src="https://img.logo.dev/stripe.com?token=LOGO_DEV_PUBLISHABLE_KEY"
  loading="lazy"
  alt="Stripe logo"
/>
Want to store logos on your own infrastructure? Pro and Enterprise plans include data caching licenses. See self-hosting.
