Frequently asked questions
How do I convert decimal to hex?
Divide the number by 16 repeatedly, writing down the remainders (10–15 become A–F) from last to first. For example 255 ÷ 16 = 15 r15 → FF. Or paste it into the converter and read the hex instantly.
What is 255 in hex?
255 (decimal) is FF in hexadecimal — two hex digits, the maximum value of one byte.
Do I get an uppercase or lowercase hex result?
The converter shows uppercase hex (FF). Hex is case-insensitive, so ff and FF are the same value — lowercase it if your code style requires.
