🎯 What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text in computers and electronic devices. Each character is assigned a unique number from 0 to 127, making it possible for different systems to communicate and exchange text data reliably.

⚙️ How It Works

Our ASCII converter transforms characters into their numerical representations or vice versa. When converting text to ASCII, each character is mapped to its corresponding code. For ASCII to text, numerical codes are converted back to readable characters. The tool supports multiple number systems including decimal, hexadecimal, binary, and octal.

🔢 Number Systems

Decimal: Base-10 (0-9)
Hexadecimal: Base-16 (0-9, A-F)
Binary: Base-2 (0-1)
Octal: Base-8 (0-7)

Each system offers different representations of the same ASCII values, useful for various programming and data processing contexts. Base-10 (0-9)
Hexadecimal: Base-16 (0-9, A-F)
Binary: Base-2 (0-1)
Octal: Base-8 (0-7)

Each system offers different representations of the same ASCII values, useful for various programming and data processing contexts.

💡 Common Uses

ASCII conversion is essential in programming, data encoding, debugging, network protocols, file format analysis, and understanding character encoding issues. It's particularly useful for developers working with text processing, data transmission, and cross-platform compatibility.

📚 Character Ranges

0-31: Control characters
32-126: Printable characters
48-57: Digits (0-9)
65-90: Uppercase letters (A-Z)
97-122: Lowercase letters (a-z)

Special characters include punctuation, symbols, and mathematical operators. Control characters

🔐 Extended ASCII

While standard ASCII uses 7 bits (0-127), extended ASCII uses 8 bits (0-255), adding 128 additional characters including accented letters, box drawing characters, and special symbols. Unicode has largely superseded extended ASCII for international text representation.

Frequently Asked Questions

❓ What is the difference between ASCII and Unicode?

ASCII is a 7-bit character encoding standard supporting 128 characters, primarily covering English letters, digits, and basic symbols. Unicode is a much larger standard supporting over 140,000 characters from multiple languages and symbol sets. ASCII is a subset of Unicode, meaning all ASCII characters have the same code points in Unicode.

❓ How do I convert text to ASCII codes?

Simply enter your text in the input field, select your preferred number format (decimal, hexadecimal, binary, or octal), and the conversion happens automatically in real-time. Each character will be converted to its corresponding ASCII code in the selected format. You can then copy or download the results.

❓ Can I convert ASCII codes back to text?

Yes! Select the 'ASCII → Text' mode and enter your ASCII codes separated by spaces or delimiters. The tool will automatically detect the format and convert the codes back to readable text. Make sure your codes are within the valid ASCII range (0-127 for standard ASCII).

❓ What are control characters in ASCII?

Control characters (ASCII 0-31) are non-printable characters used for text formatting and device control. Examples include newline (10), tab (9), carriage return (13), and escape (27). These characters control how text is displayed or processed rather than representing visible symbols.

❓ Why use hexadecimal or binary representations?

Different number systems serve different purposes in programming. Hexadecimal is compact and commonly used in color codes, memory addresses, and low-level programming. Binary directly represents how computers store data. Decimal is most human-readable. Octal is sometimes used in Unix file permissions and legacy systems.
