The Text to Hexadecimal Converter tool transforms text characters into their hexadecimal representations. This versatile converter is essential for developers, digital forensics experts, and system administrators who need to work with different data encodings and analyze binary data.
Instantly converts text to hexadecimal with auto-convert functionality, providing immediate feedback as you type.
Toggle between displaying hex values with or without the '0x' prefix to suit different use cases and format requirements.
Support for file uploads, URL-based loading, and downloading conversion results for batch processing.
Real-time size and character count metrics for both input and output, helping track data transformations.
Each character in text is converted to its corresponding hexadecimal value based on its ASCII/Unicode code point. Here's a conversion table showing common examples:
| Character | Decimal (ASCII) | Hexadecimal | With 0x Prefix |
|---|---|---|---|
| H | 72 | 48 | 0x48 |
| e | 101 | 65 | 0x65 |
| l | 108 | 6C | 0x6C |
| o | 111 | 6F | 0x6F |
| space | 32 | 20 | 0x20 |
// Convert character to hexadecimal function charToHex(char) { let hex = char.charCodeAt(0).toString(16); return hex.length === 1 ? '0' + hex : hex; } // Process entire string function convertText(input, showPrefix) { return input .split('') .map(char => { let hex = charToHex(char); return showPrefix ? '0x' + hex : hex; }) .join(' '); }The auto-convert feature monitors input changes in real-time, providing instant hex conversion while typing. This can be toggled off for better performance with large text inputs.
The converter tracks key metrics for both input and output:
