About this tool: UTF-8 ↔ Hex Converter
Encode UTF-8 text as hexadecimal bytes or decode a valid UTF-8 byte sequence.
UTF-8 encodes a character as one to four bytes, so an emoji produces several hexadecimal pairs. Whitespace between byte pairs is ignored when decoding. Invalid hexadecimal or invalid UTF-8 is rejected instead of silently replacing characters.
