Fun Fact
Base64 increases file size by about 33%, but it became widely popular because early internet systems could only reliably transmit text data. This encoding made binary files portable across email and legacy communication protocols.
Historical Context
Base64 encoding emerged in the early days of email standards such as MIME in the 1990s. It was designed to ensure binary attachments could travel safely through systems built only for ASCII text. Today, it remains essential in web development, APIs, and cloud architectures.
