How to convert

Positional base conversion in both directions, plus a worked example.

hexadecimal = convert(binary digits → integer → hexadecimal digits)

binary = convert(hexadecimal digits → integer → binary digits)

Positional bases use place values, not a single multiplier. Each binary digit is parsed against base 2, converted to an exact integer, then written in hexadecimal.

To go the other way, parse hexadecimal digits, convert to the same integer, and format in binary. The live converter handles both directions.

Worked example on this page:

11111111 binary = FF hexadecimal

About these units

Short background on the units used in this conversion.

Binary (Base-2)

Binary (Base-2) uses positional notation in base 2. Each digit position represents a power of the base — this is notation, not a currency or measurement unit.

Binary is the native language of digital logic — bits, registers, and machine code.

Hexadecimal (Base-16)

Hexadecimal (Base-16) expresses the same integer value using a different radix. The numeric value is identical; only the digit representation changes.

Hex output is standard when working with bytes, colors, and low-level debugging.

Frequently asked questions

How do I convert binary to hexadecimal?
Enter a valid binary integer in the From field. The converter parses each digit against the source base, converts through an exact BigInt value, and formats the result in hexadecimal. Example: 1010 binary = a hexadecimal.
What happens if I type an invalid digit?
Invalid digits are rejected with an inline message — for example, "2" in binary or "G" in hexadecimal — instead of showing a misleading result.
Is this Binary to Hexadecimal converter private?
Yes. All calculations run locally in your browser. Nothing you type is sent to a server.
