What is Hex Converter?
Hexadecimal (base-16) represents binary data using digits 0–9 and letters A–F, where each hex digit encodes exactly 4 bits and each byte (8 bits) is represented by two hex digits. Hex is widely used in computing: memory addresses and machine code are displayed in hex, CSS color codes (#ff5733) are hex RGB values, cryptographic hashes (MD5, SHA-256) are hex-encoded byte arrays, and network protocol debuggers display packet data as hex dumps. Converting text to hex reveals the underlying byte values of each character, which is useful for debugging encoding issues, analyzing binary file formats, and working with low-level protocols.
