Enter a binary value and get its exact hex value, grouped in fours for easy checking.
Binary digits only (0 and 1). The leftmost group is padded with zeros to 4 bits. Conversion runs in your browser, so nothing is uploaded.
Binary is base 2, and hex is base 16. Because 16 is 2 to the power of 4, every hex digit matches exactly 4 binary bits, which makes binary to hex conversion a simple grouping job. The Binary to Hex Converter does that grouping for you.
It also shows the padded groups, so you can see exactly how each group became its hex digit.
Group the bits in fours, starting from the right. If the leftmost group has fewer than 4 bits, pad it on the left with zeros. Convert each group of 4 bits to its hex digit, where 1010 is A, 1011 is B, 1100 is C, 1101 is D, 1110 is E, and 1111 is F. Read the hex digits from left to right.
Yes, it is completely free with no sign up and no limits. You can convert as many binary values as you like.
Yes. You can enter a binary value with or without the 0b prefix, for example 0b1010 or 1010, and both give A.
The tool pads the leftmost group with zeros until it has 4 bits. Padding on the left does not change the value, and the grouping working is shown.
Yes. The converter uses BigInt arithmetic, so very long binary values convert exactly, with no rounding.
Hex to binary is the reverse direction. You can also go from binary to decimal with the Binary to Decimal Converter.
No. All conversion happens in your browser on your own device, so your values never leave your computer.
To get the decimal value instead, try the Binary to Decimal Converter, and for the reverse hex direction, try the Hex to Decimal Converter.
