Fun Fact

Base64 increases the size of data by about 33% because it converts binary information into plain text characters that can be safely transmitted over systems that only support text content.

Historical Context

Base64 encoding was originally introduced as part of the MIME standard in the early days of the internet to allow binary data to be transmitted over email systems that only supported plain text. Converting Base64 back into UTF-8 text remains a fundamental task in modern computing, especially in web development, APIs, and data exchange formats.
