Convert text to binary (01001000…) and binary back to text. Runs entirely in your browser.
Each character in a text string has an ASCII (or Unicode) code point. This tool converts each character to its 8-bit binary representation, separated by spaces. For example, "Hi" becomes "01001000 01101001".
Common uses: Computer science homework, data encoding, understanding how computers store text, CTF challenges, and learning binary number systems.
