Binary Translator
Translate text to binary (8-bit bytes), or decode binary back to text - supports full Unicode via UTF-8 encoding.
Recommended Settings
Pro Tips
- •Each character becomes one or more 8-bit bytes, separated by spaces, using standard UTF-8 encoding
- •This supports full Unicode, including emoji and non-Latin scripts, not just basic ASCII letters
- •Use Swap Direction to instantly flip the current output into the new input for a quick round-trip check
- •Binary input must use spaces between each 8-bit byte to decode correctly
Most Popular
Most users start by translating a short word or their name to see the byte pattern
When to Use This Tool
Demonstrate how text is represented as binary data at the byte level.
See how UTF-8 encodes different characters, including multi-byte ones like emoji.
Encode a clue or message in binary for a puzzle or game.
Encode a name or short message in binary for a tattoo, gift, or keepsake.
How It Works
Encode the input text into UTF-8 bytes, then convert each byte to its 8-bit binary representation
Join the resulting binary bytes with spaces
For decoding, reverse the process by parsing each binary group back into a byte and decoding the byte sequence as UTF-8

Frequently Asked Questions
Does this support emoji and non-English text?
Yes, since it uses standard UTF-8 encoding, any Unicode character - including emoji and non-Latin scripts - can be represented, sometimes using multiple bytes per character.
Why do some characters produce more than one byte group?
UTF-8 uses variable-length encoding - basic Latin characters use 1 byte, while many other characters and emoji require 2 to 4 bytes.
What format should binary input be in?
Space-separated 8-bit byte groups, like '01001000 01101001' - each group represents one byte of the encoded text.
Is my data sent to a server?
No. Translation happens entirely in your browser.
What's the difference between this and UTF8 Encoder?
This tool displays bytes in binary (base-2) format, while UTF8 Encoder displays them in hexadecimal (base-16) - both represent the same underlying byte data.
