Why Use SVG Data URIs?

An SVG Data URI embeds the entire SVG directly into CSS or HTML. This eliminates external requests, leading to faster loading times for your website icons and graphics. It is crucial for modern performance scores.

Single Request: The browser loads the image content with the main CSS file.
Better Performance: Reduces network latency and overhead, boosting Core Web Vitals scores.

Percent-Encoded vs. Base64

Percent-Encoded (Recommended): Generally smaller and preferred for CSS injection. It replaces reserved characters (like #, <, >) with their hexadecimal equivalents (e.g., %23, %3C).
Base64: Converts the binary data into an ASCII string. While universally compatible, it can be 20-30% larger than the percent-encoded version.
