Hex to Text Converter
Hex with or without spaces
How It Works
- Step 1: Enter hexadecimal string (pairs of hex digits like 48656C6C6F) with or without spaces, 0x prefix, or delimiters for conversion to ASCII text.
- Step 2: The converter parses hex string removing spaces and prefixes, then groups characters into 2-digit pairs representing single bytes (00-FF range).
- Step 3: Converts each hex pair to decimal value (48 hex = 72 decimal), then maps to ASCII character using standard character encoding table (72 = 'H').
- Step 4: Displays decoded text with character-by-character breakdown showing hex value, decimal equivalent, and resulting ASCII character for debugging and learning.

✓ Reverse engineer binary protocols
✓ Solve CTF encoding challengesKey Changes:
The converter transforms hexadecimal representation to human-readable ASCII text using base-16 to base-10 conversion. Each hex pair (2 characters) represents one byte—48 hex equals 0x48 or 72 decimal, which maps to ASCII 'H'. The conversion uses positional notation: 48 hex = 4×16 + 8×1 = 72 decimal. The tool handles various hex formats: continuous (48656C6C6F), spaced (48 65 6C), or prefixed (0x48 0x65). Space character (0x20, decimal 32) is preserved in conversion, maintaining word boundaries. The hex range 00-7F covers standard ASCII (0-127), while 80-FF covers extended ASCII (128-255) for international characters. Uppercase and lowercase hex letters (A-F, a-f) are treated identically—6C and 6c both decode to 'l'. This conversion is fundamental to debugging—network analyzers display packet data as hex, requiring conversion to read text content. Developers use hex-to-text converters to decode HTTP headers in packet captures, extract strings from binary files, reverse engineer proprietary protocols, and solve CTF challenges involving hex-encoded flags. The tool demonstrates why hexadecimal is preferred for binary data—more compact than binary (4 bits per character vs 8), more readable than decimal for byte-aligned data.
Frequently Asked Questions
How do I convert hexadecimal to text?
Paste your hexadecimal string (with or without spaces) into the input field and click "Convert to Text". The tool automatically decodes the hex values into ASCII text characters.
What is hexadecimal encoding?
Hexadecimal (hex) is a base-16 number system that represents binary data in a more readable format. Each pair of hex digits represents one byte (8 bits) which corresponds to an ASCII character. For example, "48" in hex equals "H" in ASCII.
Can I convert hex with or without spaces?
Yes! The converter automatically handles hex input with spaces (48 65 6C 6C 6F) or without spaces (48656C6C6F). It intelligently parses the hex string regardless of formatting.
Why would I need to convert hex to text?
Hex encoding is commonly used in programming, web development, debugging, URL encoding, color codes, and data transmission. Converting hex to text helps decode encoded messages, debug applications, and understand data formats.
Is this hex to text converter secure?
Yes, completely secure. All conversion happens entirely in your browser using JavaScript. Your hex data never leaves your device, is never sent to any server, and is never stored or logged.
What if my hex string has invalid characters?
The converter validates your input and will show an error if non-hexadecimal characters are detected. Valid hex uses only digits 0-9 and letters A-F (case insensitive).
