Binary to Hex Online

Updated 2026-10-24

Convert binary to hexadecimal online for free. Paste a binary value (spaces between groups are fine) and SnapTools shows its hex representation instantly, in your browser. Nothing you enter is uploaded.

Long binary strings are hard to read, so they are almost always written in hex, where every four bits collapse into a single digit. This converter does that grouping for you, turning a wall of ones and zeros into a compact hex value ready to copy: handy for byte values, colours, and low-level debugging. For every base at once, use the Number Base Converter.

// how to use

  1. 1 Paste or type a binary value into the input (spaces between groups are fine).
  2. 2 SnapTools converts it to hexadecimal as you type.
  3. 3 Copy the hex result, or open the Number Base Converter for all bases at once.

// faq

Where does the word "nibble" for 4 bits come from?
A 4-bit value, half a byte, is called a nibble because "byte" was already a play on the word "bite." Programmer David Benson is credited with coining the joke around 1958, and it stuck as the standard name for exactly one hex digit worth of bits.
How do I convert binary to hex by hand?
Starting from the right end, split the bit string into chunks of four, padding a short chunk on the left with zeros, and each chunk translates straight to one hex digit (1111 becomes F, 1010 becomes A). This tool takes care of the chunking, so there is no need to count bit positions by hand.
Is the output upper or lower case?
Hex letters are shown in upper case (FF, not ff), the most common convention for byte and colour values. Either case means the same number.
Can I include spaces between bytes?
Yes. Spaces separating your binary groups are ignored, so you can paste readable byte-spaced binary straight in.
What if my input is not valid binary?
Binary only uses the digits 0 and 1. Any other character is flagged so you can fix it instead of getting a wrong result.
