Binary to Hex Converter
Hexadecimal is a compact way to write binary — every 4 bits become one hex digit. This converter collapses long bit strings into short, readable hex. Everything runs locally in your browser.
Binary (base 2) in, Hex (base 16) out.
How it works
Group the bits into nibbles of four from the right and convert each: 1111 1010 → f a → "fa". Pad the left group with zeros if it is short.
Examples
- 1010102a
- 11111111ff
- 10000000000400
FAQ
How do I convert binary to hexadecimal?
Group the bits into nibbles of four from the right and convert each: 1111 1010 → f a → "fa". Pad the left group with zeros if it is short. Or just paste your binary value into the box above and the hexadecimal result appears instantly.
Does this Binary to Hex converter run in my browser?
Yes. The conversion happens entirely client-side — nothing you type is uploaded — and it uses big-integer math, so even very long binary numbers convert exactly.
What is the largest number I can convert?
There is no practical limit. Because the converter works with arbitrary-precision integers, a binary value of any length converts without rounding or overflow.
