appkiro.comBase Converter switches a non-negative integer between decimal, hexadecimal, binary, and octal in real time, lets you flip individual bits, and provides a small bitwise calculator (AND, OR, XOR, NOT, shift left, shift right) for register-style work.
0x, binary recognises 0b, and octal recognises 0o. They are stripped before parsing and added back when copying.5 AND 3.No. The hex, binary, and octal fields accept either bare digits or values that include the standard prefix. The Copy button always returns the value with its prefix attached.
It shows the lowest 16 bits of the current decimal value. Click any cell to flip that bit, and every base updates to match. The grid hides automatically once a value goes above 65,535.
JavaScript bitwise NOT operates on signed 32-bit integers, so the result is shifted into an unsigned 32-bit range for display. Any value larger than 0xFFFFFFFF is masked off.
No. The converter parses non-negative integers only. Fractional digits and signs are rejected, and bitwise operations require operands that fit in 32 unsigned bits.
No. Parsing and conversion run with built-in JavaScript number methods inside your browser, with nothing transmitted.
