Binary is the fundamental language of computers — a base-2 number system using only two digits: 0 and 1. Every piece of data your computer processes, from text messages to streaming video, is ultimately stored and transmitted as sequences of binary digits (bits).
In text encoding, each character is assigned a numeric value, which is then represented in binary. For example, the letter "A" is 65 in decimal, which translates to 01000001 in binary. Our converter handles this translation instantly for any text you provide.
How Binary to Text Conversion Works
Converting binary to text is a three-step process:
Split the binary string into groups (typically 8 bits per character for ASCII/UTF-8)
Convert each binary group to its decimal equivalent
Map each decimal value to its corresponding character using the encoding table (ASCII, UTF-8, etc.)
For example: 01001000 01101001 → 72, 105 → "Hi"
Supported Number Systems
Beyond binary, this tool converts between multiple number systems commonly used in programming and computer science:
Decimal (Base-10): The standard number system (0–9). Each ASCII character maps to a decimal value (A=65, Z=90, a=97).
Hexadecimal (Base-16): Uses digits 0–9 and letters A–F. Compact representation — every byte is two hex digits (A=41, Z=5A).
Octal (Base-8): Uses digits 0–7. Common in Unix file permissions and some legacy systems (A=101, Z=132).
Frequently Asked Questions
How do I convert text to binary?
Type or paste your text into the input field above. The tool instantly converts each character to its binary representation (8-bit ASCII/UTF-8). For example, "Hello" becomes "01001000 01100101 01101100 01101100 01101111". All processing happens in your browser — no data is sent to any server.
How do I convert binary to text?
Switch to "Binary → Text" mode using the direction toggle. Paste your binary string (space-separated groups like "01001000 01100101" or continuous like "0100100001100101"). The tool auto-detects the format and converts it to readable text instantly.
What is binary code?
Binary is a base-2 number system using only two digits: 0 and 1. Computers store all data in binary — every letter, number, image, and program is ultimately represented as sequences of 0s and 1s. In text encoding, each character maps to a binary number: "A" = 01000001, "B" = 01000010, etc.
What encodings are supported?
The tool supports ASCII (7-bit, 128 characters), UTF-8 (variable width, supports all Unicode characters), and UTF-16 (16-bit encoding). ASCII is default and works for English text. Use UTF-8 for international characters, emojis, and special symbols.
Can I convert between binary and other number systems?
Yes! Use the conversion mode selector to convert between text, binary, decimal, hexadecimal, and octal. The "All Formats" panel shows simultaneous conversions to every supported format.
What do the separator and grouping options do?
The separator option controls how binary groups are displayed: space (01001000 01100101), comma, or no separator. Grouping controls bit width: 8-bit (standard byte), 4-bit (nibble), or 16-bit. Padding ensures each group has the full number of bits (e.g., "A" shows as 01000001 instead of 1000001).
Is this tool free?
100% free, forever. No signup, no usage limits, no premium tier. The tool runs entirely in your browser using JavaScript — we don't have a server to bill you for. Convert as much as you need.
