Turn text into binary, hexadecimal, octal or decimal codes per character, and decode them back (UTF-8 aware).
About Text ↔ binary
Computers store letters as numbers. This shows your text as Binary (01000001), Hex (41), Octal (101) or Decimal (65), either from UTF-8 bytes (Thai uses 3 bytes per letter) or from each character's Unicode code point.
Paste space-separated numbers and press “To text” to decode.
