Base Converter (2-36)
A general-purpose number-base converter that handles any radix from 2 (binary) up to 36 (digits 0-9 then letters a-z). Enter a value, the base it's currently in, and the target base. The tool also shows the value in the four standard bases (binary, octal, decimal, hex) for quick reference. Powered by BigInt so arbitrarily large numbers convert without precision loss. Runs entirely in your browser.
