How large a number can it handle?

It uses JavaScript BigInt, so there is no fixed bit-width limit — conversions stay exact for arbitrarily large integers.

Does it support negative numbers?

Yes. Prefix the value with a minus sign in any base; the bitwise panel also works on negative operands using BigInt semantics.

Number Base Converter

Convert numbers between binary, octal, decimal, and hexadecimal in real time, and run bitwise operations (AND, OR, XOR, NOT, and shifts). Arbitrary-precision via BigInt, so even very large integers convert exactly — entirely in your browser.

How to use Number Base Converter

Type a number into any base field — the others update instantly.
Use 0b, 0o, or 0x prefixes if you like; a leading minus is allowed.
Open the bitwise calculator to AND/OR/XOR/shift two values and copy the result.
