How to convert text to binary

  1. Choose Text to binary or Binary to text.
  2. Type your text, or paste the binary (spaces between bytes are optional).
  3. Copy or download the result.

How it works

Each character is stored as one or more bytes in UTF-8, the encoding used by web pages and most files. A byte is 8 binary digits, so "H" is 01001000 (72). Letters with accents take 2 bytes and emoji 4, so they become longer runs of bits.

Good to know

  • Binary without spaces is read 8 digits at a time.
  • Hex, octal and decimal bytes are understood too, with or without 0x and 0b prefixes.
  • Bytes that don't form a valid character are shown as �.
