Binary Code Translator
Convert text into binary, or decode binary back into readable text. Switch direction, type or paste, and copy the result. The translation runs entirely in your browser.
How binary represents text
Computers store every character as a number. This translator uses each character’s Unicode code point and writes it as an 8-bit binary value — so the letter A (code point 65) becomes 01000001. Space-separating each byte keeps the output readable and lets the decoder split it back apart cleanly.
Decoding binary
To go the other way, paste groups of binary digits separated by spaces. The decoder reads each group as a base-2 number and maps it back to its character. Standard ASCII characters fit in 8 bits; characters above code point 255 are written with as many bits as they need.
Common uses
Students use it to learn how text maps to bits, hobbyists hide short messages in binary, and developers use it to sanity-check character encoding. Because nothing is uploaded, it’s safe for quick, private conversions.
