How to convert binary to hexadecimal
To convert binary to hexadecimal, type your number in the converter above and read the hexadecimal value. For example, 1101 0110 in binary is D6 in hexadecimal. The other bases are shown at the same time.
Why convert binary to hexadecimal
Hexadecimal is shorthand for binary, so converting binary to hex makes long strings of bits readable: 11010110 becomes D6, and a 32-bit mask becomes just eight characters. It is the standard way to show bit patterns in documentation, debuggers and datasheets.
Convert binary to hexadecimal by hand
Here is 1101 0110 (binary) converted step by step:
- Group the bits in fours from the right: 1101 0110.
- Convert each group to one hexadecimal digit: 1101 = D → 0110 = 6.
- Join the digits: D6.

Check your answer
To check the result, convert it back: D6 in hexadecimal is 1101 0110 in binary. Your input may only contain the binary digits 0 1; any other character is not a valid binary number.
Good to know
- Always group from the right; pad the left with zeros to complete the last group.
- A byte is always exactly two hex digits.
- The table is worth memorising: 1010 is A and 1111 is F.
- The converter also shows the other bases at the same time, so a single entry gives you binary, decimal, hexadecimal and octal.

Frequently asked questions
How do I convert binary to hexadecimal?
Type the number in the converter at the top of this page and read the hexadecimal value. For example, 1101 0110 (binary) is D6 (hexadecimal).
Why do programmers prefer hex to binary?
Hex is four times shorter and each digit maps cleanly to four bits, so it is easy to convert by eye.
What if my binary length is not a multiple of four?
Pad with zeros on the left. For example, 110 becomes 0110, which is 6.
How many bits does 1101 0110 need?
1101 0110 is 214 in decimal, which needs 8 bits in binary.
Is this converter free and private?
Yes. It is free, needs no sign-up and works in your browser, so what you type is never sent to a server.
