Computers store every letter, digit, and symbol as binary — sequences of ones and zeros. Converting text to binary reveals how that works, and it is handy for puzzles, learning, and low-level programming. Our free text to binary translator converts in both directions and also supports decimal, octal, and hexadecimal.
How Text Becomes Binary
Every character has a numeric code point defined by the Unicode standard (the first 128 of which match ASCII). To convert text to binary, each character's code point is written in base 2. For example, the letter "A" has code point 65, which in 8-bit binary is 01000001.
A word like "Hi" becomes two binary groups:
H = 01001000
i = 01101001
How to Convert Text to Binary Online
- Choose a direction — Text to Encoded, or Encoded to Text.
- Pick a base — binary, decimal, octal, or hexadecimal.
- Type or paste your text and see it convert instantly.
- Choose a separator — space, comma, newline, or none — to format the output.
- Copy the result with one click.
The tool also shows a handy reference table breaking down each character's code point across bases.
Why Convert Text to Binary?
Learning and education — Seeing text as binary makes the concept of character encoding concrete and tangible.
Puzzles and games — Binary messages are popular in escape rooms, geocaching, and coding challenges.
Programming — Understanding how characters map to code points helps when working with encodings, bitwise operations, and data formats.
Curiosity — Discover what your name or a message looks like in the language computers actually use.
Binary, Decimal, Octal, and Hex
The same character can be encoded in several bases. For "A" (code point 65):
- Binary: 01000001
- Decimal: 65
- Octal: 101
- Hexadecimal: 41
Our tool supports all four, so you can encode and decode in whichever base you need.
Frequently Asked Questions
