About this tool
Convert text to binary code and binary code back to text with our free online binary converter. Transform any text, letters, numbers, or symbols into their binary representation (8-bit ASCII codes composed of 0s and 1s), or decode binary strings back into human-readable text. Perfect for learning binary code, computer science education, programming exercises, data encoding, or just having fun with binary translations.
Our binary converter supports bidirectional conversion: encode text to binary by converting each character to its 8-bit binary ASCII representation, or decode binary strings by converting groups of 8 binary digits back to their corresponding characters. The tool handles all ASCII characters including letters (uppercase and lowercase), numbers, punctuation, symbols, and special characters.
Essential for computer science students learning about binary and ASCII encoding, programmers working with low-level data representation, educators teaching number systems and computer fundamentals, cybersecurity enthusiasts exploring encoding methods, and anyone curious about how computers represent text internally. The tool provides multiple output formats for flexibility.
All conversions happen instantly in your browser with complete privacy - no data is sent to any server. No registration required, no character limits, works on all devices, and functions offline. Free to use unlimited times for educational or personal purposes.
Usage examples
Convert Simple Word to Binary
Input: "Hello"
Binary: "01001000 01100101 01101100 01101100 01101111" Each letter converted to 8-bit binary: H=01001000, e=01100101, l=01101100, o=01101111
Convert Number to Binary
Input: "123"
Binary: "00110001 00110010 00110011" ASCII codes: 1=49=00110001, 2=50=00110010, 3=51=00110011
Decode Binary to Text
Binary input: "01001000 01101001"
Decoded text: "Hi" 01001000 = 72 (ASCII) = H, 01101001 = 105 (ASCII) = i
Convert Sentence with Spaces
Input: "OK GO"
Binary: "01001111 01001011 00100000 01000111 01001111" O=01001111, K=01001011, space=00100000, G=01000111, O=01001111
Convert Special Characters
Input: "!@#"
Binary: "00100001 01000000 00100011" !=33=00100001, @=64=01000000, #=35=00100011

FAQs
How does text to binary conversion work?
Each character is converted to its ASCII decimal value (0-127), then that decimal number is converted to an 8-bit binary representation. For example, the letter "A" has ASCII value 65, which in binary is 01000001. Each character becomes 8 binary digits (bits), forming a byte.
What is the difference between ASCII and binary?
ASCII is a character encoding standard that assigns decimal numbers (0-127) to characters. Binary is the base-2 number system using only 0 and 1. When we "convert text to binary," we're actually converting text to ASCII values, then representing those ASCII values in binary format. They're related but different concepts.
Why are there 8 digits for each character in binary?
Standard ASCII uses 8 bits (1 byte) per character, allowing for 256 possible values (0-255). The original ASCII standard only used 7 bits (128 values), but 8-bit representation became standard for computer memory efficiency. Each group of 8 binary digits represents one character.
Can I convert binary back to text?
Yes! Select "Binary to Text" mode and paste your binary code. The tool accepts binary with or without spaces. It groups the binary digits into 8-bit chunks, converts each chunk to its decimal ASCII value, then displays the corresponding character. For example, 01001000 01101001 decodes to "Hi".
What happens with non-English characters or emojis?
This tool converts characters using their Unicode code points. Characters beyond ASCII (0-127) like é, ñ, ü, and emojis will be converted but may produce more than 8 bits. For example, emoji code points can be in the thousands. The tool handles them but won't follow strict 8-bit ASCII format. Results work best with basic ASCII characters.
How do spaces appear in binary?
The space character has ASCII value 32, which in binary is 00100000. When converting text with spaces, you'll see this binary pattern for each space. For example, "A B" converts to "01000001 00100000 01000010" (A, space, B).
Can I use this for programming or data encoding?
Yes! This tool is useful for understanding how text is stored in computers, testing binary data, learning about character encoding, or creating binary representations for educational purposes. However, for production programming, use your language's built-in encoding functions which handle extended character sets.
What if my binary string is invalid?
If your binary input contains characters other than 0, 1, or spaces, or if the total number of bits isn't divisible by 8, the tool will show an error. Each character must be represented by exactly 8 bits. Remove any invalid characters and ensure you have complete 8-bit sequences.
