Hex to String Converter Online

What is this Hex to String Tool?

  • Converts hexadecimal values to human-readable text
  • Supports multiple character encodings (UTF-8, ASCII, ISO-8859-1, etc.)
  • Handles various data formats including binary data and special characters
  • Auto-cleans input from non-hex characters
  • Supports file-to-hex conversion

How to Use:

  1. Enter hex values in the input box (with or without separators)
  2. Select desired text encoding from the dropdown
  3. Click Convert to see the decoded text
  4. Use Copy button to save results
  5. Load files directly using the file input

Understanding Hexadecimal Encoding

Hexadecimal (base16) is a numerical system widely used in programming and digital systems. Each hex digit represents 4 bits (0-9 and A-F), making it more compact than binary representation. Key technical aspects:

  • Character Encoding Compatibility: UTF-8 handles 93% of web content, while ASCII is suitable for basic English text
  • Byte Alignment: Hex values must form complete bytes (2 hex digits per byte)
  • Endianness: UTF-16/32 require correct byte order (Big-Endian vs Little-Endian)

Hex Conversion FAQ

How are invalid hex characters handled?

Our tool automatically filters non-hex characters (0-9, A-F). Example: Input "48!e@6c" becomes "486c".

Why do I get garbled text?

Common causes: 1. Incorrect encoding selection 2. Incomplete bytes 3. Unsupported characters. Try UTF-8 first.

File conversion limitations?

Supports text files up to 10MB. Binary files are converted to their hex representation for decoding.

Encoding Standards Comparison

Encoding Characters Supported Common Usage Byte Length
UTF-8 Full Unicode Web, Modern Apps 1-4 bytes
ASCII 128 English Basic Text 1 byte
GBK Simplified Chinese Chinese Systems 2 bytes
Shift_JIS Japanese Legacy Systems 1-2 bytes
