Char to ASCII Converter - Convert Characters to ASCII Codes Online

The Char to ASCII Converter is an online tool that converts characters to their corresponding ASCII (American Standard Code for Information Interchange) codes. This tool provides detailed information about each character including its ASCII code in decimal, hexadecimal, binary, and octal formats, making it invaluable for developers, programmers, and anyone working with character encoding.

What is this tool for?

Our Char to ASCII Converter tool is perfect for developers, programmers, students, and anyone who needs to understand character encoding. Whether you're debugging character-related issues, learning about ASCII encoding, working with character manipulation, or converting text for programming purposes, this tool provides comprehensive character information.

Common use cases include:

Converting characters to ASCII codes for programming and development
Understanding character encoding and ASCII values
Debugging character-related issues in code
Learning about ASCII character set and encoding
Converting text to ASCII codes for data processing
Analyzing character properties and types

How to Use the Tool

Enter your text: Type or paste the characters you want to convert into the input box. You can enter single characters, words, sentences, or entire paragraphs.
Set separator (optional): Choose how you want the ASCII codes separated in the output (space, comma, etc.). The default is a space.
View results: The tool automatically displays:
- ASCII codes in your chosen format
- Detailed character information table showing each character's position, ASCII code (decimal), hexadecimal, binary, octal, and character type
- Statistics about ASCII and non-ASCII characters
Copy results: Use the copy button to copy the ASCII codes to your clipboard.

Understanding ASCII Codes

ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text in computers and other devices. ASCII uses 7 bits to represent 128 different characters, including:

Control characters (0-31): Non-printable characters used for device control
Printable characters (32-126): Letters, numbers, punctuation, and symbols
Extended ASCII (128-255): Additional characters (not part of standard ASCII)

Character Representations

The tool displays each character in multiple formats:

Decimal: The standard ASCII code (0-127 for standard ASCII)
Hexadecimal: Base-16 representation (0x00-0x7F for standard ASCII)
Binary: Base-2 representation (8-bit binary format)
Octal: Base-8 representation (3-digit octal format)

Example

If you enter the character "A":

Character: A
ASCII (Decimal): 65
Hexadecimal: 0x41
Binary: 01000001
Octal: 0101
Type: Uppercase Letter

If you enter "Hello":

H → 72 (0x48, 01001000, 0110)
e → 101 (0x65, 01100101, 0145)
l → 108 (0x6C, 01101100, 0154)
l → 108 (0x6C, 01101100, 0154)
o → 111 (0x6F, 01101111, 0157)

Character Types

The tool automatically categorizes characters into different types:

Number: Digits 0-9 (ASCII codes 48-57)
Uppercase Letter: A-Z (ASCII codes 65-90)
Lowercase Letter: a-z (ASCII codes 97-122)
Space: Space character (ASCII code 32)
Symbol: Punctuation and special characters
Control Character: Non-printable control characters (0-31)
Non-ASCII: Characters beyond the standard ASCII range (128+)

Frequently Asked Questions

What is the difference between ASCII and Unicode?

ASCII is a 7-bit encoding that represents 128 characters, primarily English letters, numbers, and basic symbols. Unicode is a much larger character encoding standard that can represent over 1 million characters, including characters from all languages and scripts. ASCII is a subset of Unicode - the first 128 Unicode characters are identical to ASCII.

Can I convert multiple characters at once?

Yes! You can enter any text - single characters, words, sentences, or entire paragraphs. The tool will convert each character individually and display detailed information for all of them in a comprehensive table.

What happens with non-ASCII characters?

Non-ASCII characters (those with codes above 127) are still converted and displayed, but they are marked as "Non-ASCII" in the character type column. The tool shows their Unicode code point values in all formats (decimal, hex, binary, octal).

How do I use the ASCII codes in my code?

You can use ASCII codes in various ways depending on your programming language. For example, in JavaScript you can use String.fromCharCode(65) to get 'A', or 'A'.charCodeAt(0) to get 65. The tool provides codes in multiple formats (decimal, hex, binary, octal) for different use cases.

What are control characters?

Control characters (ASCII codes 0-31) are non-printable characters used for device control. Examples include newline (10), carriage return (13), tab (9), and null (0). These characters are displayed in the table but shown as their type name rather than the actual character since they're not printable.

Can I upload a file to convert?

Yes, the tool supports file upload. You can upload a text file and the tool will convert all characters in the file to their ASCII codes, displaying detailed information for each character.
