What is Hex Encoding?

Hexadecimal encoding converts each byte of data into a two-character hex string (00–ff). This is useful for inspecting binary data, debugging network protocols, and representing byte arrays in code.

UTF-8 characters that use more than one byte will produce multiple hex pairs.
