What is Base64 Encoding? Base64 is a binary-to-text encoding scheme that represents binary data using a set of 64 printable ASCII characters (A–Z, a–z, 0–9, +, and /), with = used for padding. The name comes from the 64 characters used in the alphabet. Each Base64 character encodes exactly 6 bits of binary data, meaning every 3 bytes of input become 4 Base64 characters — increasing the data size by approximately 33%. Base64 was standardized in RFC 4648 and is universally supported across programming languages, browsers, and operating systems. ...
