Questions
Which bases does this converter support?
It supports integer conversion between bases 2 through 36, with common presets for binary, octal, decimal, hexadecimal, and base 36.
Can this convert very large integers?
Yes. The converter uses BigInt so large integers can be converted without normal JavaScript number precision loss.
Does Utilumo upload my input?
No. Utilumo has no backend that could receive your input. Where a tool makes a request as part of its function, it goes directly from your browser to the destination you choose, never through Utilumo.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
