What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It translates 24-bit binary packages into groups of four 6-bit characters. It is commonly used to embed images/files inside HTML, CSS, or JSON packages safely without corruption.
URL-Safe Base64 (RFC 4648)
Standard Base64 contains the characters `+` and `/`, which have special meanings inside URI querystrings and filepaths. URL-safe Base64 substitutes `+` with `-` (hyphen) and `/` with `_` (underscore), and strips the trailing padding `=` (equals sign) to make URLs clean and safe to transmit.
