Convert between hexadecimal and text formats with multiple output options

What is Hexadecimal?

Hexadecimal (hex) is a base-16 number system that uses 16 symbols: 0-9 and A-F. It's commonly used in programming and computer science because it provides a more human-readable representation of binary data. Each hex digit represents exactly 4 bits (binary digits).

Hex Digits

0 = 0
1 = 1
2 = 2
3 = 3
4 = 4
5 = 5
6 = 6
7 = 7
8 = 8
9 = 9
A = 10
B = 11
C = 12
D = 13
E = 14
F = 15

Example Conversion

Text: Hello
ASCII: 72 101 108 108 111
Hex: 48 65 6C 6C 6F
Combined: 48656C6C6F

Common Use Cases

Programming

Represent memory addresses, color codes, and binary data in a readable format

Web Development

CSS color codes, URL encoding, and JavaScript string manipulation

Cryptography

Represent hash values, keys, and encrypted data in a compact format

Database

Store binary data, UUIDs, and handle character encoding issues

Debugging

Analyze binary files, network packets, and memory dumps

File Formats

Work with binary file headers, metadata, and file signatures

How Hex to Text Conversion Works

1

Parse Hex Pairs

Split the hexadecimal string into pairs of characters (e.g., "48 65 6C")

2

Convert to Decimal

Each hex pair represents a decimal value (48₁₆ = 72₁₀)

3

Map to ASCII

Convert decimal values to their corresponding ASCII characters (72 = "H")

4

Combine Characters

Join all converted characters to form the final text string

This is a subset of ASCII characters. The full ASCII table contains 128 characters (0-127).

Tips and Best Practices

For Developers

  • Always validate hex input before conversion
  • Handle odd-length hex strings appropriately
  • Consider character encoding (UTF-8 vs ASCII)
  • Use proper error handling for invalid input

Common Formats

  • Continuous: 48656C6C6F
  • Space separated: 48 65 6C 6C 6F
  • With prefix: 0x48 0x65 0x6C
  • Escaped: \\x48\\x65\\x6C

Hex in Programming Languages

JavaScript

// Hex to text
parseInt('48', 16) // 72
String.fromCharCode(72) // 'H'
// Text to hex
'H'.charCodeAt(0).toString(16) // '48'

Python

# Hex to text
bytes.fromhex('48656C6C6F').decode()
# Text to hex
'Hello'.encode().hex()
