What is HEX to ASCII Converter?

A browser-based tool that converts hexadecimal data to ASCII text instantly. Perfect for analyzing memory dumps, network packets, and binary log files commonly encountered in development work.

Hexadecimal input is converted to ASCII text in real-time. It supports various input formats including space-separated, comma-separated, and 0x-prefixed values, so you can simply copy and paste data without reformatting.

How to Use

Enter hexadecimal values in the input area and they will be automatically converted to ASCII text.

Conversion Example

Input: 48 65 6C 6C 6F 20 57 6F 72 6C 64
Output: Hello World

Simply copy hexadecimal data from memory dumps or log files and paste it to convert into human-readable text.

Supported Input Formats

Compatible with various hexadecimal formats, so you don't need to worry about formatting.

  • Space-separated - 48 65 6C 6C 6F
  • No spaces - 48656C6C6F
  • 0x prefix - 0x48 0x65 0x6C 0x6C 0x6F
  • Comma-separated - 48, 65, 6C, 6C, 6F
  • 0x + comma - 0x48, 0x65, 0x6C, 0x6C, 0x6F
  • Multi-line data - Can process multi-line data such as memory dumps

Both uppercase and lowercase hexadecimal values are supported, so there's no need to standardize the format.

Use Cases

Debugging

When examining memory dumps or binary file contents, you can convert hexadecimal data into readable text. This is particularly useful when analyzing memory contents after a program crash.

Network Packet Analysis

Packet data captured by tools like Wireshark often displays payload sections in hexadecimal format. This tool quickly converts that data to reveal the text content that was transmitted.

Log File Inspection

Some system logs and application logs output binary data in hexadecimal format. Using this tool, you can read the strings and messages recorded in those logs.

Protocol Development and Testing

During communication protocol development or testing, you can verify that byte sequences are correctly converted to the expected strings.

Hexadecimal and ASCII Relationship

ASCII characters have values from 0 to 127, each represented in hexadecimal notation. For example, the letter 'H' is 72 in decimal and 48 in hexadecimal.

Hex: 48 → Decimal: 72 → Character 'H'
Hex: 65 → Decimal: 101 → Character 'e'
Hex: 6C → Decimal: 108 → Character 'l'
Hex: 6F → Decimal: 111 → Character 'o'

This tool converts hexadecimal notation back to original characters, making binary data human-readable.
