Fun Fact
Base64 encoding increases the size of data by about 33%, because it represents binary information using only printable ASCII characters. Despite the overhead, it remains one of the most widely used encoding formats on the internet.
Historical Context
Base64 was originally introduced to safely transmit binary data over communication systems that were designed to handle only plain text. Early email systems and internet protocols could not reliably process raw binary information, so Base64 became a universal solution.
Today, it is still heavily used in email attachments, data URIs, authentication tokens, and many modern web technologies where safe text-based transport of binary data is required.
