The Text to Hex Converter is a fundamental tool for developers working with hexadecimal encoding and data representation. It converts text characters to their hexadecimal representation (2 hex digits per character) and vice versa. Perfect for debugging, data analysis, and understanding hexadecimal encoding.
Convert text to hexadecimal and hex back to text. Useful for encoding. All in your browser.

Select 'Text to Hex' mode and enter your text. The tool converts each character to its hexadecimal representation. Each character is converted to a 2-digit hex number (e.g., 'A' becomes '41').
Select 'Hex to Text' mode and enter hexadecimal digits (with or without spaces). Each pair of hex digits represents one character. The tool converts them back to readable text.
Hexadecimal (hex) is a base-16 number system using digits 0-9 and letters A-F. It's commonly used in programming to represent binary data in a more readable format. Each character is represented by 2 hex digits (1 byte).
Yes! Toggle the 'Uppercase' option to convert hex output to uppercase letters (A-F) or keep it lowercase (a-f). The converter accepts both uppercase and lowercase hex input.
Yes! Our text to hex converter is 100% free with no registration required, no usage limits, and no hidden fees. You can convert as much text as you need for your development work.
No, all text conversion happens locally in your browser. We don't store, save, or have access to any text you convert. Your privacy is completely protected.
The tool uses ASCII/UTF-8 encoding, where each character is represented by 2 hexadecimal digits (1 byte). This is the standard encoding used by most computer systems and programming languages.
Hex output can be formatted with or without spaces. Each character becomes a 2-digit hex number (e.g., 'A' = 41). You can choose uppercase or lowercase hex output for consistency.
Yes! Select 'Hex to Text' mode and paste your hexadecimal digits (with or without spaces). The tool will convert each pair of hex digits back to its corresponding character.
If the hex string contains invalid characters or has odd length, the tool will show an error message. Make sure hex input contains only 0-9 and A-F (or a-f), and has even length (2 digits per character).
Hexadecimal is more compact and readable than binary. One hex digit represents 4 bits, so 2 hex digits represent 1 byte. It's commonly used in programming, debugging, and data representation.
