Binary ↔ Hex Converter

How to Convert Binary to Hex Manually

Hexadecimal exists to make binary readable. Every hex digit represents exactly four bits, so converting binary to hex simply means grouping the binary digits in sets of four — starting from the right — and translating each group to its hex symbol.

Take the binary value 11010110. Split it into nibbles from the right: 1101 and 0110. The nibble 1101 equals 13 in decimal, written as D in hex, while 0110 equals 6. The result is D6. This binary to hex converter performs that grouping automatically, even for very long values.

• Group the binary digits into sets of four, starting from the rightmost bit.
• Pad the leftmost group with leading zeros if it has fewer than four bits.
• Convert each four-bit group to its decimal value (0-15).
• Replace values 10-15 with the letters A-F.
• Concatenate the hex symbols from left to right.

How to Convert Hex to Binary Manually

To go the other way, replace each hex symbol with its four-bit binary equivalent: 0 becomes 0000, 1 becomes 0001, and so on up to F becoming 1111. This hex to binary converter applies that rule instantly and also shows you the decimal value for verification.

For example, the hex value A5 becomes the binary 10100101 because A is 1010 and 5 is 0101. The one-to-four mapping between digits is what makes binary and hex such natural companions in computing.

Where Binary and Hex Are Used Together

Binary-to-hex conversion appears everywhere in systems programming: reading network packets, inspecting memory dumps, configuring registers, and debugging protocols. Hex lets you express an eight-bit byte as just two characters instead of eight.

Keep this binary to hex converter handy whenever you work with bit manipulation, embedded systems, or any tooling that reports values as raw binary data.
