This calculator converts binary code into readable text, e.g. 01001000 01101001 = "Hi".

Binary is how computers represent every character you type, with each letter, digit, or symbol stored as an 8-digit sequence of 0s and 1s corresponding to its ASCII code. This calculator reverses that process — paste in binary code as space-separated 8-bit groups, and it decodes each group back into the readable text it represents. It's the natural counterpart to the Text to Binary Converter, useful for anyone learning how computers encode text, debugging binary data, or just curious what a string of 1s and 0s actually says.

  • Format: each group of up to 8 binary digits (0s and 1s) is treated as one character's ASCII code.
  • Example: 01001000 = 72 = "H", 01101001 = 105 = "i" → "Hi".
  • Separation required: groups must be separated by spaces so the calculator knows where each character's code begins and ends.

What if my binary code is all one continuous string with no spaces?

Insert spaces every 8 digits first, since this calculator relies on spaces to split characters.

What does "Invalid input" mean?

It means one of the groups contains characters other than 0 and 1, or is longer than 8 digits.
