Fun Fact
A Base64 string is roughly 33% larger than the original binary file. That means encoding images to Base64 trades file size for convenience, which is why it is best used for small icons and simple graphics rather than large photos.
Historical Context
Base64 encoding originated in the early days of email systems when binary attachments could not be reliably transmitted over text-only protocols. Engineers needed a way to convert binary data into safe ASCII characters that could pass through legacy networks without corruption.
Over time, Base64 became a universal method for embedding binary assets such as images, documents, and media into text formats like HTML, XML, and JSON. Today it remains a core technology used across web development, APIs, and data exchange systems worldwide.
