Hexadecimal bytes and text
Each pair of hex digits represents one byte. For example, A is 41 in ASCII and UTF-8, while the word Hi is 48 69. UTF-8 symbols and emoji may need multiple byte pairs.

How to convert text to hex
Example
EncodeLab 45 6e 63 6f 64 65 4c 61 62 - Text is encoded into UTF-8 bytes by your browser.
- Each byte becomes two hexadecimal digits from 00 through FF.
- Spaces keep each byte visually separate without changing its value.
Spaces and 0x notation
This tool displays byte pairs with spaces for readability. The bytes keep the same value without spaces; when sharing individual values, 0x41 is another common way to write hex 41.
Text to hex versus a hex number converter
Text to Hex Converter writes one or more UTF-8 bytes for each character. Hex to Decimal works with one whole number, so FF means 255 there; it does not mean the text character FF.
