What is the maximum number size?

The tool uses JavaScript BigInt for conversion, supporting arbitrarily large integers limited only by your browser memory.

Does it support fractional (decimal point) numbers?

The current version supports integer conversion only. Floating-point base conversion requires additional precision settings and is planned for a future update.

Number Base Converter

Converts numbers between the four most common numeral bases simultaneously: binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16). All four representations update in real time as you type. Also supports custom base conversion (base 2–36).

Binary (Base 2)

Octal (Base 8)

Decimal (Base 10)

Hexadecimal (Base 16)

Supports integers up to 2⁵³−1. Negative numbers: prefix with − in decimal.

Enter any number in any base and see all other representations update instantly.
