Binary Code Translator
Translate text to binary code and binary back to text. Convert any text to 0s and 1s instantly.
What is Binary Code?
Binary code represents data using only two digits: 0 and 1. Every character in a computer is stored as a sequence of bits (binary digits). In the ASCII encoding, each character is represented by 8 bits (1 byte), giving 256 possible values (0–255).
For example, the letter "A" has the ASCII code 65, which in binary is 01000001. "Hello" in binary is: 01001000 01100101 01101100 01101100 01101111.
How to Use
- Choose Text → Binary or Binary → Text mode
- Type or paste your input
- The result appears instantly (live mode)
- Optionally enable the character table to see each character's code
- Copy or download the result
Frequently Asked Questions
Why are there 8 bits per character?
8 bits (1 byte) can represent 256 different values (0–255), which is enough for all standard ASCII characters. For Unicode/UTF-8, some characters use 2, 3, or 4 bytes.
What separators are supported for Binary → Text?
The converter auto-detects spaces, commas, and dashes. It also handles unseparated binary (every 8 characters is one byte).
Can I convert emoji to binary?
Emoji and extended Unicode characters use multiple bytes in UTF-8. This tool uses the JavaScript charCodeAt() API which handles the Basic Multilingual Plane but may not represent all emoji correctly.
What is the difference between bits and bytes?
1 byte = 8 bits. In this tool, each character is converted to 8 bits. So "Hello" (5 chars) = 40 bits = 5 bytes.
Is this tool suitable for learning binary?
Yes! The character table feature shows exactly how each character maps to its binary representation, making it ideal for learning about computer encoding.
