ASCII Converter

🔤 What is ASCII?

ASCII (American Standard Code for Information Interchange) is a 7-bit character encoding standard that represents text in computers and electronic devices. Developed in the 1960s, ASCII assigns unique numerical values (0-127) to letters, digits, punctuation marks, and control characters.

Each ASCII character occupies exactly one byte of memory, making it extremely efficient for text storage and transmission. The ASCII table includes:

  • Control characters (0-31): Non-printable characters like newline, tab, carriage return
  • Printable characters (32-126): Letters, numbers, punctuation, and symbols
  • Extended ASCII (128-255): Additional characters in some implementations

⚙️ How This ASCII Converter Works

Our ASCII converter supports bidirectional conversion between text and ASCII codes with flexible input formats and comprehensive error handling. The tool provides multiple output modes: hexadecimal, decimal, binary, and octal representation.

  • Quad Format Support: Choose between hexadecimal, decimal, binary, and octal representation
  • Customizable Output Styles: Select prefix styles for each format (0x vs x vs \x for hex, 0b vs b for binary, 0o vs o vs \ for octal)
  • Flexible Input Parsing: Support for various hex formats, space-separated decimals, and 8-bit binary strings
  • Real-time Error Feedback: Instant validation with detailed error messages and visual indicators
  • ASCII Table Viewer: Interactive reference table showing all ASCII characters with their codes
  • Extended ASCII Support: Handle characters in the 128-255 range with appropriate fallbacks
  • Smart Input Recognition: Automatically detect and parse mixed hex formats
  • Copy with Feedback: Click any output field to copy results with visual confirmation
  • Multiple Outputs: Add up to 10 different format outputs simultaneously

📋 ASCII Table Reference

The complete ASCII character set contains 128 characters (0-127). This interactive table shows each character with its decimal, hexadecimal, binary values, and descriptions. Control characters (0-31) and DEL (127) are highlighted in gray.

Understanding these character codes is essential for programming, data processing, and text manipulation. Each character has a unique code that computers use internally to represent text.
