Text to Binary
Convert any text into 8-bit binary code with a single click, byte by byte.
About Text to Binary
A text-to-binary converter turns ordinary words into the 8-bit binary representation computers actually store, which is both an educational tool and a practical utility. Whether you're preparing a puzzle for students, checking how a character encodes, or just curious about the machine-level view of your name, this tool produces the binary form instantly, byte by byte.
Each character maps to its numeric code, which is then written as an 8-bit binary number. The letter O is code 79, which is 01001111 in binary, and ASCII text converts one byte per character. Non-ASCII characters such as accented letters and emoji are encoded as their multi-byte UTF-8 sequences, so the binary output can be longer than 8 bits per character, matching what a real file would store.
Computer science students use it to see concretely how text becomes bits, and teachers use it to generate examples and exercises for lessons on binary and encoding. Puzzle makers create binary-coded clues, and developers debugging encoding issues inspect how specific characters are stored. Anyone wanting to verify that their mental conversion is right will appreciate the instant byte-by-byte answer.
How to Use
- Type or paste the text you want to convert.
- Press Convert to Binary.
- Copy the binary output or download it for your own use.
Example
"OK" 01001111 01001011
Each character maps to its 8-bit binary representation: O is 01001111 and K is 01001011.
FAQ
Why 8 bits per character?
8 bits is the standard size of one byte, which is how text is stored in ASCII and UTF-8 encodings.
Can this convert emoji?
Yes. Non-ASCII characters are encoded as their multi-byte UTF-8 sequences, producing more than 8 bits per character.
Is binary still used today?
Yes — it's fundamental to how computers store everything. Learning to read binary text is a classic computer science exercise.
Why do emoji produce much longer binary than letters?
Emoji aren't in the 8-bit ASCII table, so UTF-8 encodes each one as a 4-byte sequence, giving 32 binary digits instead of 8. The longer output is the standard representation.
Is this the binary a file on disk contains?
Very close. Files store text as these same UTF-8 bytes. Some editors add a byte-order mark at the start, but the per-character bytes match what this tool produces.
