Base16 (Hex) Converter

How Base16 (Hex) works

Base16 uses 16 symbols 0-9 and A-F to represent bytes.
Each byte (8 bits) splits into two 4-bit nibbles; each nibble maps to one hex digit.
Example: byte 0x4F → binary 0100 1111 → hex "4F".
Decoding groups every two hex digits into one byte; spaces/newlines are ignored.
Hex is a representation, not encryption; it does not provide confidentiality.
