Binary to Hex
FREEPaste in a binary number and get the hexadecimal value straight away. This binary to hex converter also shows how the bits were grouped, so you can check the result or learn the method as you go. It's free, runs in your browser, and needs no account.
How to Use the Binary to Hex Converter
1. Type or paste your binary number into the input box. Only 0 and 1 are accepted, and anything else is flagged as you type.
2. Read the hex result, which appears immediately.
3. Open the step-by-step breakdown to see how the bits were split into groups of four and matched to hex digits.
4. Switch between uppercase and lowercase, or turn on spaced grouping if you're working with a long value.
The converter accepts binary integers up to 64 bits, plus fractional values such as 1101.1011.
How Binary to Hexadecimal Conversion Works
Hexadecimal is base 16, and 16 is 2⁴. So every hex digit stands for exactly four binary bits, and the conversion needs no arithmetic, only grouping.
1. Starting from the right, split the binary number into groups of four bits.
2. If the leftmost group is short, pad it with zeros on the left.
3. Replace each group with its hex digit.
Example: 11010110
Groups: 1101 0110
Hex: D 6
Result: D6
Example with padding: 101101
Padded: 0010 1101
Hex: 2 D
Result: 2D
Example with a fraction: 1101.1011
Whole part 1101 = D
Fraction 1011 = B
Result: D.B
Example with a short fraction: 0.101
Padded on the right: 0.1010
Fraction 1010 = A
Result: 0.A
For fractions, the whole part is grouped from the right and the fractional part from the left, starting at the point. If the last fractional group is short, zeros are added at the end.

Binary to Hexadecimal Calculator for Everyday Work
A binary to hexadecimal calculator saves time whenever a value arrives as a long string of ones and zeros. Instead of grouping bits by hand and checking each nibble against a table, enter the number once and read the result. The same goes for anyone looking for a quick bin to hex converter: the breakdown is there if you want to verify the steps, and out of the way if you don't.
Why Use Hex Instead of Binary?
Binary is how computers store data, but it's hard for people to read. A single byte takes eight digits, and a 32-bit address takes thirty-two. Hex expresses the same value in a quarter of the length, with no loss of information.
You'll run into it in memory addresses in debuggers, CSS color codes like #FF5733, MAC and IPv6 addresses, register values, and hash strings.
Binary Coded Hexadecimal: What People Usually Mean
"Binary coded hexadecimal" is a common way of describing a binary value written in hex, and that is exactly what this tool produces. It is not the same as binary-coded decimal (BCD), a separate encoding in which each decimal digit is stored in its own four bits. If you need a straight base-2 to base-16 conversion, you are in the right place.
Common Mistakes to Avoid
❌ When Converting Binary to Hex
✓ Solution:
Grouping from the left. Always group from the right. If the length isn't a multiple of four, pad zeros on the left, or every digit after the first shifts.
Dropping leading zeros. 0001 0110 and 10110 give the same value, but dropping zeros before grouping can misalign the nibbles if you do it by hand.
Mixing up hex and decimal. 1010 is A in hex and 10 in decimal. Check which base your output is in.
Entering a stray character. A 2, a letter, or a symbol makes the input invalid. The tool catches this as you type.
Frequently Asked Questions
Split the binary number into groups of four bits from the right, pad the leftmost group with zeros if needed, and replace each group with its hex digit. For example, 11010110 becomes 1101 0110, which is D6.
The method is the same: group in fours from the right, then look up each group. The table above covers all sixteen possibilities, from 0000 (0) to 1111 (F).
Because 16 = 2⁴. Four bits can represent sixteen different values, and hex has exactly sixteen digits, 0 through F. That's why the conversion is exact and works in both directions.
Yes. Enter a value such as 1101.1011 and the tool converts the whole and fractional parts separately, giving D.B.
They mean the same thing. Uppercase (C3) is common in documentation and programming, while lowercase (c3) is common in web color codes. Choose whichever suits your project.
People often use the phrase to mean converting binary to hexadecimal, and that's what this tool does. It isn't binary-coded decimal (BCD), which is a different encoding.
Up to 64 bits.
No. The conversion runs in your browser, so nothing you enter leaves your device.
