Base64 Encoding Explained: Binary Data over Text Transports

How Base64 Operates

Base64 groups binary data into 6-bit chunks and maps each chunk to one of 64 ASCII characters (A-Z, a-z, 0-9, +, /). Because 3 bytes (24 bits) become 4 ASCII characters, Base64 increases data size by approximately 33%.
