How to Use Number Base Converter

  1. 1

    Enter a number

    Input a number in any base: decimal (0-9), hexadecimal (0-9, A-F), binary (0-1), or octal (0-7).

  2. 2

    Select input base

    Specify which base the input is in. The tool auto-detects common formats (0x for hex, 0b for binary, 0o for octal).

  3. 3

    Choose output bases

    Select one or multiple target bases. The tool shows conversions to all popular bases simultaneously.

  4. 4

    View all conversions

    See decimal, hexadecimal, binary, and octal representations side-by-side. Useful for debugging, bitwise operations, and protocol work.

  5. 5

    Copy any format

    Click individual bases to copy their value to clipboard. Perfect for embedding color codes (#FF5500), bitmasks, or IP addresses.

Frequently Asked Questions

How do I convert hex to decimal?
Enter your hex value, select base 16 as input, and the decimal output appears instantly alongside binary and octal representations. You can also prefix with 0x.
Can I see the binary bits visually?
Yes, the bit visualization displays individual bits as colored boxes in 8-bit, 16-bit, or 32-bit views. Bits are grouped into nibbles (groups of 4) for readability.
Does it support bitwise operations?
Yes — AND, OR, XOR, NOT, left shift, and right shift operations between two values. Results are displayed in all bases simultaneously.
Can it handle large numbers?
Yes, the converter uses BigInt for numbers that exceed the standard 32-bit or 64-bit range, supporting arbitrarily large integers.
What bases are supported?
Any base from 2 to 36, with presets for Binary (2), Octal (8), Decimal (10), and Hexadecimal (16). Custom base input is available for specialized conversions.
