What is Base64?

Base64 is a coding system that converts binary data (like images or files) into an ASCII text string.

It is fundamental in web development for embedding small resources directly into HTML or CSS, avoiding extra HTTP requests.

Data URIs: Use Base64 to put images directly in `img src="..."`.
Compatibility: Transmit binary data via media that only support text.

Usage Example (CSS)


.icon { 

  background-image: url("data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAAB...");
 }
