Text to Hex Converter
Frequently Asked Questions
What is the difference between text to hex and text to binary conversion?
Both conversions represent text as numeric codes, but hex uses base 16 (digits 0–9 and A–F) while binary uses base 2 (only 0s and 1s). Hex is more compact — two hex digits represent the same value as eight binary digits, making it far easier to read and work with in code.
Does this converter support Unicode and special characters?
Yes. The converter supports the full UTF-8 character set. Standard ASCII characters (0–127) encode as a single two-digit hex byte. Extended Unicode characters such as accented letters, emoji, or symbols encode as multiple bytes in UTF-8, each represented by two hex digits in the output.
How do I convert hex back to text?
Use a Hex to Text converter, which is simply the reverse operation. Parse each pair of hex digits as a byte value, then map each byte back to its corresponding ASCII or Unicode character. Many online tools, including this site, offer both directions so you can encode and decode in one place.
Why does the space character appear as '20' in hex output?
The space character has ASCII code 32 in decimal. Converting 32 to hexadecimal: 32 divided by 16 equals 2 remainder 0, giving hex 20. Every printable space in your input string will appear as the two-character sequence '20' in the hex output, which is completely normal and expected behavior.
Can I use text-to-hex conversion for passwords or sensitive data?
Hex encoding is not encryption — it is a reversible transformation that anyone can decode. Never treat hex-encoded data as secure or hidden. For protecting sensitive data, use proper cryptographic hashing (SHA-256, bcrypt) or encryption algorithms instead. This tool is intended for encoding and development tasks, not security.
