Text to Binary Converter
Convert text to binary and binary back to text.
Words as ones and zeros
Every character is stored as a number, and every number as binary, so any text can be written as a string of ones and zeros. This converts text into that binary form and back, which is handy for a puzzle, a lesson in how computers represent text, or decoding a binary message someone has sent you.
Paste text to get binary, or binary to get the text back.
Eight bits to a character
The way it works is that each character maps to a number through a standard like ASCII, and that number is written in binary — usually eight bits, or one byte, for a basic character. So the letter A, which is sixty-five, becomes eight ones and zeros. Seeing the conversion makes an abstract idea tangible: the text on your screen really is just numbers underneath, and those numbers really are just patterns of on and off, which is the whole foundation of how computers store everything.
Common questions
How does a letter become binary?
Each character maps to a number through a standard like ASCII, and that number is written in binary, usually eight bits per basic character.
Can it convert binary back to text?
Yes — paste in the ones and zeros and it reconstructs the original text.
Is anything uploaded?
No. The conversion happens in your browser.
