About this tool
Encode any text as its hexadecimal byte sequence (UTF-8), or decode a hex string back to text. Handy when reading wire formats, hex dumps, or working with crypto / firmware tooling.
FAQs
What encoding does the text use?
UTF-8. So 'A' is 41 and 'é' is c3 a9.
Can I paste with spaces or 0x prefixes?
Yes - spaces, newlines, and a leading 0x are stripped before decoding.
What if the hex is invalid?
An odd length or non-hex character shows an inline error - nothing else changes.
