Binary to Hex Converter
Binary and hexadecimal fit together neatly: every group of four bits maps to exactly one hex digit. That makes hex a much shorter way to write the same value a string of 0s and 1s represents.
Enter a binary string below and the hexadecimal equivalent appears instantly. The tool checks that you have entered only 0s and 1s, and the conversion runs entirely on your device.
| Binary (nibble) | Hex | Decimal |
|---|---|---|
0000 | 0 | 0 |
1010 | A | 10 |
1111 | F | 15 |
11111111 | FF | 255 |
00010000 | 10 | 16 |
11111111→FFSplit into nibbles 1111 1111, each maps to F.
Frequently asked questions
How do I convert binary to hex quickly?
Group the bits into nibbles of four from the right (pad the left with zeros if needed), then translate each nibble to its hex digit. 1111 1111 becomes FF.
Why is binary-to-hex so direct?
Because 16 is 2⁴, four binary digits always correspond to exactly one hex digit. No arithmetic is needed beyond a small lookup, unlike converting to decimal.
What if my bit count is not a multiple of four?
The leftmost group is simply padded with leading zeros. For example 1 0000 (five bits) is treated as 0001 0000 and becomes 10.
