About This Calculator
This text to binary converter maps each character to its 8-bit binary byte.
Text is encoded as UTF-8: ASCII letters become a single byte (e.g. A = 01000001), while emoji and accents span multiple bytes. Space-separated bytes keep the result readable; the continuous option produces a single string.
Encoding runs entirely in your browser.

Frequently Asked Questions
Why is each letter 8 bits?
Each ASCII character is stored in one byte, which is 8 bits. So A is 01000001, B is 01000010, and so on.
Can I decode binary back to text?
Yes — use the companion text-to-binary reverse tool, "Binary to Text", which decodes 8-bit groups back into characters.
