What is Binary Code?
Binary code is a system of representing text, numbers, or computer processor instructions using the binary number system's two binary digits: 0 and 1. Each binary digit is called a bit. Computers use binary because they are built from electronic switches that can only be in two states: ON (1) or OFF (0).
How Binary Translation Works
Our translator uses the ASCII (American Standard Code for Information Interchange) standard, which assigns each character a unique number from 0 to 127. For example, the letter 'A' is 65 in decimal, which becomes 01000001 in binary (8-bit). Each character in your text is converted to its ASCII decimal value, then to binary.

Understanding ASCII
ASCII (American Standard Code for Information Interchange) is the standard for character encoding. Here are key ASCII values:
- Uppercase letters: A=65, B=66, ... Z=90
- Lowercase letters: a=97, b=98, ... z=122
- Numbers: 0=48, 1=49, ... 9=57
- Space: 32
- Common punctuation: !=33, "=34, #=35, $=36, %=37, &=38, '=39, (=40, )=41, *=42, +=43, ,=44, -=45, .=46, /=47
Binary Number System Basics
Binary is a base-2 number system. Each digit represents a power of 2: the rightmost digit is 2⁰ (1), next is 2¹ (2), then 2² (4), 2³ (8), 2⁴ (16), 2⁵ (32), 2⁶ (64), and 2⁷ (128). To convert a binary number to decimal, add up the values of positions with 1s. For example, 01000001 = 0×128 + 1×64 + 0×32 + 0×16 + 0×8 + 0×4 + 0×2 + 1×1 = 64 + 1 = 65 (which is 'A' in ASCII).
Binary Translation Modes
- Text to Binary: Converts readable text into 8-bit binary code. Each character becomes 8 binary digits.
- Binary to Text: Converts 8-bit binary sequences back into readable text. Spaces between bytes are optional.
- Space Separator: Adds spaces between binary bytes for readability. Turn off for compact output.
- 8-bit Padding: Ensures every binary byte has exactly 8 digits. Standard for modern computing.
Frequently Asked Questions
What is binary code?
Binary code is the fundamental language of computers, using only two digits: 0 and 1. Every piece of data in a computer is ultimately stored and processed as binary.
Why 8 bits per character?
Standard ASCII uses 7 bits, but 8-bit (1 byte) has become the standard because it allows for extended ASCII characters and aligns with computer memory architecture.
Can I translate binary without spaces?
Yes! Just uncheck the "Add space between binary bytes" option. Our tool will automatically detect 8-bit boundaries when converting back to text.
What is the ASCII table?
ASCII is the standard that maps numbers to characters. For example, 65 = 'A', 97 = 'a', 48 = '0', 32 = space. Our tool includes a complete ASCII reference table.
Is this tool free forever?
Yes — 100% free forever. No signup, no premium tier, no tracking. All processing happens in your browser.
Does it work on mobile?
Yes! Fully responsive and works perfectly on smartphones, tablets, and desktops.
Can I translate emojis?
Emojis use Unicode (multiple bytes), not standard ASCII. Our tool focuses on standard ASCII characters (0-127).
What's the difference between binary and ASCII?
ASCII is the standard that maps characters to numbers. Binary is the representation of those numbers in base-2. Together they enable text storage on computers.
