Bit Alchemist

Bit Alchemist is a fast, native programmer's calculator built for people who think in hexadecimal, binary, and bits — developers, embedded engineers, reverse engineers, and CS students.

Switch instantly between hex, decimal, octal, and binary. Choose 8-, 16-, 32-, or 64-bit word sizes with signed or unsigned interpretation, and watch every base update live as you type. Enter full C-style expressions with parentheses and correct operator precedence, or work in immediate/chain mode — one engine, one result.
