Binary Translator
Convert text, code, and numbers between binary, decimal, hexadecimal, and octal. Choose a conversion mode, enter your value, and get an instant translation — use it as an English-to-binary encoder or decoder in either direction.
Every piece of digital data on your computer — from the letters in this sentence to the pixels on your screen — is ultimately stored as a sequence of ones and zeros.
This binary translator bridges the gap between human-readable text and the machine code that computers process natively, letting you encode ASCII characters into 8-bit binary, decode binary back to English, and convert numeric values across all four standard number systems used in computing.
Converting/Translating Binary Codes for the Four Number Bases
Binary (base-2) uses only 0 and 1 and maps directly to the on/off transistor states inside a CPU. Decimal (base-10) is the everyday counting system humans use.
Hexadecimal (base-16) compresses binary into a shorter form, with each hex digit representing exactly 4 bits — making it the preferred notation for memory addresses, color codes, and byte values. Octal (base-8) groups binary into sets of 3 bits and remains common in Unix file permissions and legacy computing contexts.
How the English to Binary Encoder/Decoder Works
When you enter plain text, the translator looks up each character’s ASCII value and converts that numeric code to an 8-bit binary string.
- The capital letter “A” has an ASCII value of 65, which becomes 01000001 in binary.
- Lowercase letters, digits, spaces, and punctuation each have their own unique character codes, allowing full round-trip conversion back to readable text.
