Text and Binary Converter
Convert text into binary ones and zeros, and turn binary back into text.
How letters become numbers
Every character a computer stores is really a number, and every number is really binary — a string of ones and zeros. This converts text into that binary form and back again, so you can see the ones and zeros behind a message, decode a binary string someone sent, or use it for a puzzle, a lesson, or a bit of geeky fun.
Paste text to get its binary, or paste binary to get the text back.
What the ones and zeros mean
Under the hood, each character maps to a number through a standard like ASCII or Unicode, and that number is written in binary — typically eight bits per basic character. So the capital A is 65, which in binary is 01000001. Seeing the conversion makes the abstract idea concrete: text really is just numbers, and numbers really are just patterns of on and off.
