Developer calculator
Convert decimal, hexadecimal, binary, and octal values, then check AND, OR, XOR, NOT, and shift operations. Supports 8, 16, 32, and 64-bit widths with signed interpretation.
Base and bit calculator
Input base
Bit width
Bit operations
Second base
Check numbers, bits, and masks quickly
Use this tool when you need to move between decimal, hexadecimal, binary, and octal. Pick the input base, enter a value, and see the other base forms plus the signed interpretation at once.
Choose 8, 16, 32, or 64 bits to mask results to that width. It is useful for firmware registers, permission flags, color values, protocol fields, and any number where the bit width matters.
Apply AND, OR, XOR, NOT, left shift, and right shift directly. All calculations run in your browser, and the values you type are not sent to a server.
