Base64 is a binary-to-text encoding scheme that represents binary data as ASCII text. When you convert an image to Base64, it becomes a text string that can be embedded directly in HTML, CSS, or JSON without needing a separate image file. Data URLs include the MIME type prefix (e.g., data:image/png;base64,) making them ready for direct use in src attributes.
