Binary Text Converter
Convert text to 8-bit binary and back, one byte per character.
Text and binary, both directions
Binary is how text is actually stored — each character maps to a number, and that number to a string of ones and zeros. This tool converts your text into 8-bit binary, one byte per character separated by spaces, and converts space-separated binary back into readable text, which is handy for teaching, puzzles, or sanity-checking an encoding.
For example the letter "A" is character code 65, which is "01000001" in binary. Paste a sentence and you get a row of bytes; paste bytes and you get the sentence back.
Encoding limits and privacy
It assumes standard 8-bit bytes, so plain ASCII round-trips cleanly while characters outside that range may not map to a single byte. All conversion runs in the browser, so whatever you paste stays on your device.
Frequently Asked Questions
What format is the binary output?
Each character becomes an 8-bit byte, and bytes are separated by spaces — for example "Hi" becomes "01001000 01101001".
Can it convert binary back to text?
Yes. Paste space-separated 8-bit groups and it reassembles the original characters.
Does it handle emoji and accents?
It is built for standard 8-bit characters. Symbols outside that range may not round-trip to a single byte.
