Hex Calculator

Convert between hex, decimal, binary, and octal, run hex arithmetic and bitwise logic, and decode color hex codes to RGB and HSL.

Base Conversion Hex Arithmetic Bitwise Operations Color Hex Decoder

All-in-One Hex Calculator

Switch between base converter, hex arithmetic, bitwise logic, and color hex tools in a single interface.

You can enteres like 0x for hex, 0b for binary, or 0o for octal. Letters A–F are not case-sensitive.

Division shows integer quotient and remainder based on unsigned integer math.

Bitwise operations are computed on 32-bit unsigned values. Inputs longer than 8 hex digits are truncated to 32 bits.

You can enter formats like #7442D0, 7442D0, or #74D. Invalid hex strings will show an error.

Hex Calculator – Base Conversion, Arithmetic, Bitwise Logic, and Color Codes

This Hex Calculator is designed for developers, students, and designers who need fast conversions and operations with hexadecimal numbers. It combines a base converter, arithmetic engine, bitwise logic tool, and color hex decoder in a single interface.

Base Conversion Between Hex, Decimal, Binary, and Octal

In the Base Converter tab, you can enter a value in hex, decimal, binary, or octal and see the equivalent representation in all four bases. The calculator accepts commones like 0x for hex, 0b for binary, and 0o for octal, and normalizes letters to uppercase for hex output.

Hex Arithmetic

The Hex Arithmetic tab lets you add, subtract, multiply, or divide two hexadecimal values. The result is shown as:

  • Hexadecimal value
  • Decimal (base 10) integer
  • Binary representation
  • For division, the remainder in hex

This is useful when you are stepping through low-level calculations and want both a human-readable decimal version and machine-oriented hex and binary forms.

Bitwise Operations on Hex Values

The Hex Bitwise tab applies standard bitwise operations to two hex values:

  • A AND B
  • A OR B
  • A XOR B

It also shows the 32-bit NOT of each input. The calculator uses 32-bit unsigned integer math, which matches typical low-level usage for networking, embedded, and systems programming tasks.

Color Hex to RGB and HSL

The Color Hex tab is aimed at designers and front-end developers. Enter a color in hex form (for example #7442D0 or #3498db) and the calculator returns:

  • Hex value normalized to #RRGGBB
  • RGB values in 0–255 format
  • HSL representation
  • Normalized RGB values between 0 and 1

You also see a live color preview block rendered in the selected color. This makes it easy to decode brand colors, design tokens, or style guide values quickly.

Why Use a Hex Calculator?

Common use cases include:

  • Checking bit flags and masks in configuration or protocol fields
  • Converting addresses or offsets between hex and decimal
  • Inspecting color codes from CSS, Figma, or design systems
  • Studying number systems for computer science and math courses
