How do I convert text to binary?
Type your text and it's encoded as 8-bit binary for each UTF-8 byte; switch modes to decode binary back to text.
Does it handle emoji and accents?
Yes — it uses UTF-8, so multi-byte characters like emoji and accented letters encode and decode correctly.
Why is my binary in groups of 8?
Each byte is 8 bits; the tool can add spaces between bytes for readability or output a continuous stream.
How do I decode binary to text?
Switch to 'Binary to Text' and paste the 0s and 1s — spaces are ignored, and the length must be a multiple of 8 bits.
Is my text uploaded?
No — everything is converted locally in your browser.
