DocomintBinary to Text Converter
Convert text to 8-bit binary, or decode binary back into readable text.
Converts text to its underlying binary representation, byte by byte, using UTF-8 encoding — so accented letters and emoji round-trip correctly, not just plain ASCII. Each byte is shown as 8 bits, space-separated.
Example: "Hi!" encodes to "01001000 01101001 00100001" — three bytes, one per character.
How it works
- Type text or paste binary bytes
- Pick a direction
- The converted result appears instantly, on your device
Frequently asked questions
Why does this use UTF-8 instead of simple 7-bit ASCII codes?
UTF-8 lets accented letters, symbols, and emoji round-trip correctly — a plain ASCII-code approach would silently corrupt or drop any character outside the basic English alphabet.
Is my text uploaded anywhere?
No — Binary to Text Converter runs entirely in your browser using JavaScript/WebAssembly. Your text is never sent to a server.
What happens if I paste binary that isn't a clean multiple of 8 bits per character?
It's reported as invalid input rather than guessed at — a byte needs exactly 8 bits, so malformed binary needs to be fixed before it can decode correctly.
