Text to Hex Converter
Convert plain text to hexadecimal byte values instantly with optional separators and uppercase or lowercase output.
What Is Text to Hex Conversion?
Text to hex conversion maps each character to its byte value written in base 16. Developers use hex dumps to inspect encoding, debug protocols, and compare binary payloads without opening a hex editor.
How Text Becomes Hexadecimal
Each character is converted to its Unicode code point, then formatted as one or more hex bytes. The letter A is 41 in hex, while a space is 20.

Frequently Asked Questions
Does this tool support Unicode?
Yes. Characters outside ASCII are encoded with UTF-8 bytes, so emoji and accented letters may produce multiple hex bytes per character.
Should I use spaces between hex bytes?
Spaces make long strings easier to read. Some APIs expect a continuous string with no separator, so choose the format your system needs.
What does the 0x prefix mean?
0x is a common prefix that marks a value as hexadecimal, similar to how 0b marks binary. Enable it when your language or debugger expects that style.
Is hex case sensitive?
Hex digits are not case sensitive. 4A and 4a represent the same byte. Pick uppercase or lowercase for consistency in your project.
Can I reverse hex back to text?
Yes, with a hex-to-text decoder. Our ASCII Converter can decode hex byte lists back into readable text when values stay in range.
