Understanding Base64 Binary-to-Text Encoding
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It is widely used in email attachments (MIME), embedding Data URIs inside HTML and CSS, and passing binary tokens across JSON REST APIs.
When to Use File Data URIs
Embedding small SVG icons, sound effects, or tiny thumbnail images directly into HTML or CSS as Base64 Data URIs eliminates additional HTTP requests, speeding up initial render times for performance-critical components.
