Understanding ASCII Encoding

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns unique numeric codes to letters, numbers, punctuation, and control characters. The standard ASCII table contains 128 characters (0-127), where each character is represented by a 7-bit binary number. Extended ASCII uses 8 bits to represent 256 characters (0-255), including additional symbols and international characters.

Common Use Cases

  • •Programming & Development: Generate character codes for source code or data structures
  • •Data Encoding: Convert text to numeric format for transmission or storage
  • •Debugging: Analyze character values when troubleshooting encoding issues
  • •Education: Learn about character encoding and number system conversions
  • •Binary Analysis: Examine the binary representation of text data
  • •Protocol Implementation: Work with communication protocols that require ASCII codes

ASCII Code Ranges

0-31: Control characters (non-printable)
32: Space character
33-47: Punctuation and symbols (!, ", #, etc.)
48-57: Digits 0-9
58-64: More punctuation (:, ;, <, =, etc.)
65-90: Uppercase letters A-Z
91-96: Brackets and symbols
97-122: Lowercase letters a-z
123-127: Braces and symbols
128-255: Extended ASCII (varies by encoding)

Format Comparison

Different number systems offer various advantages depending on your use case. Decimal is the most human-readable and commonly used in general programming. Hexadecimal is compact and popular in low-level programming, memory addresses, and color codes. Binary shows the actual bit-level representation and is essential for understanding data at the hardware level. Octal is less common today but still used in Unix file permissions and some legacy systems.

Privacy & Security

All text to ASCII conversions are performed entirely in your browser using client-side JavaScript. Your data never leaves your device and is not transmitted to any server. This ensures complete privacy and security for all your conversions, making it safe to use with sensitive text.
