What is a Hex Converter?
The Hex (Hexadecimal) Converter allows you to translate between standard text (ASCII/UTF-8), decimal numbers, and Hexadecimal strings. Hexadecimal is a base-16 number system widely used in computing to represent binary data in a human-readable format.
In low-level programming, colors, memory addresses, and binary dumps are often represented in Hex. A single byte (0-255) can be perfectly represented by two hex digits (00-FF). This makes it more compact than binary and easier to read.
This tool supports multiple modes: converting text characters to their hex codes, or converting large decimal numbers to their hex equivalents (and back). It uses BigInt to support integers of arbitrary size.
1How to Use
- Select Mode: Choose 'Text ↔ Hex' for strings or 'Number ↔ Hex' for integers.
- Set Direction: Click the arrow button to swap inputs (e.g., from 'Text to Hex' to 'Hex to Text').
- Type Input: Enter your data. The tool converts as you type.
- Clean Input: The tool automatically ignores spaces or '0x' prefixes in Hex mode.
- Copy: Click the copy icon to grab the result.
★Key Features
- Four-Way Conversion: Text→Hex, Hex→Text, Number→Hex, Hex→Number.
- Large Number Support: Uses `BigInt` to handle integers larger than typical 64-bit limits.
- Auto-Sanitization: Smartly handles input with spaces or '0x' prefixes.
- Instant Feedback: Results appear immediately without page reloads.
- Unicode Support: Handles ASCII characters and basic Unicode sequences.
