Base64 Encoding

Base64 encoding is a method used to convert binary data, such as images or files, into a text format that can be easily transmitted over mediums that only support text, like emails or certain web protocols. It works by taking groups of three bytes (24 bits) from the original data and encoding them into four printable ASCII characters. This process increases the size of the data by about 33%, but it ensures the data remains intact and can be safely shared without corruption. Base64 is commonly used in web development and data storage.
