Binary to emoji converter
Turn any text into a playful emoji binary message and back. Each character is
encoded as its 8-bit binary value, then every 0 and 1 is replaced with an
emoji from the pair you choose. Great for fun social posts, secret notes between
friends, or teaching how text maps to binary.
How it works
To encode, each character’s code point is written in binary and padded to 8 bits,
producing space-separated bytes. Every 0 becomes the first emoji of your chosen
pair and every 1 becomes the second; spaces are kept as separators. To decode,
the tool reads each emoji back to 0 or 1, reassembles the 8-bit groups, and
converts each group back to a character.
Example
Encoding Hi with the 🔴/🔵 pair (🔴 = 0, 🔵 = 1):
H=01001000,i=01101001→ 🔴🔵🔴🔴🔵🔴🔴🔴 🔴🔵🔵🔴🔵🔴🔴🔵
| Character | Binary (8-bit) |
|---|---|
H | 01001000 |
i | 01101001 |
To decode, choose the same emoji pair and paste the emoji string. Everything runs in your browser with nothing uploaded.
