Binary to Text Converter — Convert Between Text and Number Systems
The Binary Text Converter is a free, instant-use tool for converting between plain text and four different number systems: binary, hexadecimal, octal, and decimal. Whether you're learning about computer science fundamentals, debugging software, working with low-level data, or just curious about how computers represent text, this tool provides instant bidirectional conversion.

Number Systems Explained
- Binary (Base-2) — Uses only 0 and 1. The fundamental language of computers. Every piece of data in a computer is ultimately represented as a sequence of binary digits (bits). Eight bits form one byte, which can represent values 0-255.
- Hexadecimal (Base-16) — Uses digits 0-9 and letters A-F. Each hex digit represents exactly 4 bits, so one byte is represented by exactly 2 hex digits. Widely used in programming for color codes (e.g., #FF5733), memory addresses, and data dumps.
- Octal (Base-8) — Uses digits 0-7. Historically important in computing, still used in Unix file permissions (e.g., chmod 755), C/C++ escape sequences, and some legacy systems.
- Decimal (Base-10) — The standard human number system. Showing ASCII/Unicode code points in decimal helps bridge between human-readable numbers and character representations.
How Text Encoding Works
Computers store text as numbers using encoding standards like ASCII and Unicode. Each character is assigned a numeric code point. For example:
- 'A' = 65 (decimal) = 01000001 (binary) = 41 (hex) = 101 (octal)
- 'a' = 97 (decimal) = 01100001 (binary) = 61 (hex) = 141 (octal)
- '0' = 48 (decimal) = 00110000 (binary) = 30 (hex) = 060 (octal)
- Space = 32 (decimal) = 00100000 (binary) = 20 (hex) = 040 (octal)
Features
