Text ⇄ Hex Converter
📖 What Is a Text to Hex Converter?
A Text to Hex Converter is a simple yet powerful tool that transforms plain text characters into their hexadecimal (base-16) representation. Every character you type — letters, numbers, symbols, even emojis — is stored in a computer as a numeric code (ASCII or Unicode). Hexadecimal is a compact, human-readable way to express those numeric codes, widely used in programming, debugging, cryptography, and data encoding.
For example, the word "Cat" converts to 43 61 74 in hexadecimal. Here, C = 43, a = 61, and t = 74 in the ASCII encoding system. This tool works both ways — you can also paste hex codes and convert them back to readable text instantly.

❓ Frequently Asked Questions
Q: What is hexadecimal?
Hexadecimal (or "hex") is a base-16 number system using digits 0-9 and letters A-F. Each hex digit represents 4 binary bits, making it a compact way to display byte values (00 to FF).
Q: Does this tool support non-English characters?
Yes! It uses UTF-8 encoding, so characters from Chinese, Arabic, Hindi, and even emojis 😊 are properly converted to their multi-byte hex sequences.
Q: What separator should I choose?
It depends on your use case. Space is the most readable. No separator gives you a continuous hex string. 0x prefix is common in C/C++ code. Percent is used in URL encoding.
