Base64 is a way to represent binary data (like images) as ASCII text. This allows images to be embedded directly in HTML, CSS, or JavaScript code without needing a separate file.
Base64 is useful for small images like icons and logos. It reduces HTTP requests. However, for large images, regular files are better as Base64 increases size by about 33%.
Base64 is the encoding method. A Data URI includes the Base64 string plus a prefix that tells the browser the content type. You need the full Data URI to embed in HTML/CSS.
There is no hard limit since everything runs in your browser. For practical use, keep Base64-encoded images under 100KB for best performance.
