Why use Data URIs?

Data URIs allow you to embed image data directly into your HTML or CSS files. This technique is especially useful for small icons, decorative elements, and critical UI components that should load immediately without waiting for extra HTTP requests.

Pros:

  • Reduced HTTP Overhead: Fewer round-trips to the server.
  • Instant Loading: Perfect for small icons and critical logos.
  • No 404 Errors: Image data is bundled with your source code.

Cons:

  • File Size: Base64 encoding increases size by approx. 33%.
  • Caching: Not cached independently from the host file.
  • Large Files: Large images can impact browser rendering speed.
