What is Base64?
Base64 encodes binary data as ASCII text. It increases file size by ~33% but lets you embed images directly in HTML, CSS, or JSON without separate file requests.
When to use it?
Ideal for small icons, thumbnails, and sprites. Avoids extra HTTP requests and simplifies deployment. Not recommended for large images due to size overhead.
