Binary to Hex Converter Tool

One binary number per line, or space-separated. Leading zeros are preserved.

Binary and Hex — A Perfect Pair

Binary and hexadecimal share a uniquely clean relationship: one hex digit maps to exactly 4 binary bits (a nibble). This means conversion requires zero arithmetic — just group bits into fours and look up the corresponding hex digit. That is why memory addresses, color codes, and bytecode are always shown in hex rather than raw binary.

Example: 11001010 → hex
1100
= 12 = C
1010
= 10 = A
11001010 binary = CA hex

Frequently Asked Questions

How do I convert binary to hexadecimal?
Group binary digits into nibbles of 4 from right to left. Each nibble maps to one hex digit: 0000=0, 0001=1 … 1010=A … 1111=F. Example: 11111111 → 1111|1111 → FF.
Why is hex useful for binary data?
One hex digit represents exactly 4 binary bits. An 8-bit byte becomes just 2 hex characters instead of 8 binary digits — 4× more compact and far easier for humans to read and compare.
What is 10101010 in hexadecimal?
Binary 10101010 equals hex AA. Split into nibbles: 1010 = A and 1010 = A. In decimal this is 170.
What is 11111111 in hex?
Binary 11111111 equals hex FF, which is decimal 255 — the maximum value a single byte can hold. You'll see FF used constantly in color codes (e.g., #FF0000 = red) and byte masks.
Can I convert multiple binary numbers at once?
Yes. Enter multiple binary numbers separated by spaces or new lines. The tool converts all of them and shows each result on its own line.
Does this support hex to binary conversion?
Yes — switch to the Hex to Binary tab. Each hex digit expands to its 4-bit binary equivalent. For example, FF → 11111111.
Is my data safe?
Yes. All processing runs entirely in your browser using JavaScript — the same privacy guarantee as our Binary to Text Converter. No data is sent to any server.
