What is Base64 format

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It is used for encoding data in a network transmission. Base64 is used to encode binary files such as images within scripts, to avoid depending on external files. The base64 format was originally designed to represent binary data in a text file format and is now widely used for encoding binary data in a number of applications, including email attachments and encoding binary data in JSON.

In Base64, each group of three bytes of binary data is split into four characters, each representing 6 bits of data, and then each group of four characters is then encoded as a sequence of 64 printable ASCII characters. The encoding process results in a compact representation of the original data and is often used to encode data that needs to be transmitted over text-based protocols like HTTP or email.
