What is ASCII?
ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text in computers and other devices. Each character is assigned a unique number from 0 to 127.
Developed in the 1960s, ASCII became the foundation for character encoding in modern computing. It includes letters (A-Z, a-z), numbers (0-9), punctuation marks, and control characters.
ASCII Character Ranges:
- 0-31: Control characters (non-printable)
- 32-47: Symbols and punctuation
- 48-57: Numbers (0-9)
- 65-90: Uppercase letters (A-Z)
- 97-122: Lowercase letters (a-z)
- 123-127: Additional symbols
Examples
Example 1: Simple Text
Hi → 72 105
Example 2: Word with Numbers
Code123 → 67 111 100 101 49 50 51
Example 3: Decoding ASCII
72 101 108 108 111 → Hello

How to Use the ASCII Converter
Text to ASCII Code Conversion
Converting text to ASCII codes is simple with our ASCII converter tool. Just type any text, and each character will be converted to its ASCII code value. For example, the letter "A" converts to ASCII code 65, while "a" converts to 97.
ASCII to Text Decoding
To decode ASCII codes back to text, enter ASCII numbers separated by spaces. Our ASCII decoder will instantly convert the codes to readable characters. This is perfect for decoding ASCII messages or debugging character encoding issues.
ASCII Converter FAQ
What does ASCII stand for?
ASCII stands for American Standard Code for Information Interchange. It's a character encoding standard that assigns numeric codes to letters, numbers, and symbols. The ASCII table includes 128 characters, with codes ranging from 0 to 127.
What is the ASCII code for common characters?
Common ASCII codes include: Space (32), 0-9 (48-57), A-Z (65-90), a-z (97-122). Special characters like ! (33), @ (64), and # (35) also have specific ASCII values. Use our ASCII chart above for a complete reference.
How do I convert ASCII to text?
To convert ASCII to text, enter the ASCII numbers (separated by spaces) into our converter. For example, "72 101 108 108 111" converts to "Hello". Our ASCII to text converter handles the conversion automatically.
What's the difference between ASCII and Unicode?
ASCII uses 7 bits and supports 128 characters, mainly for English text. Unicode is a much larger character set that includes characters from all world languages, emojis, and symbols. ASCII is a subset of Unicode, so ASCII codes are the same in both systems.
Is this ASCII converter free?
Yes! Our ASCII code converter is completely free to use with no limits. Convert text to ASCII, decode ASCII to text, and access the full ASCII table reference without any registration or fees.
