About Base64

Base64 is a group of binary-to-text encoding schemes that represent binary data.

The term Base64 originates from a specific MIME content transfer encoding. Each non-final Base64 digit represents exactly 6 bits of data. Three 8-bit bytes (i.e., a total of 24 bits) can therefore be represented by four 6-bit Base64 digits.

Base64 is designed to carry data stored in binary formats across channels that only reliably support text content.

What is the meaning of Base64?

Base64 encoding schemes are used when binary data needs to be stored or transferred as textual data. Therefore 64 characters are chosen that are both members of a subset common to most encodings (ASCII), and also printable.
