Hex Converter

Hex Converter encodes text as hexadecimal (base-16) values and decodes hex back to text. Hex is the universal language of low-level computing — memory addresses, colour codes, byte streams, and cryptographic hashes are all expressed in hex.

When debugging network protocols, binary files, or encoded data, hex gives you a compact, readable view of raw bytes without the complexity of binary notation.

Tip: Hex pairs map directly to bytes — two hex digits equal one byte. A 16-character hex string is 8 bytes of data. Use this to sanity-check lengths when working with fixed-size fields.
