How it works

Two steps, no account

1

Pick your bases

Common presets (binary, octal, decimal, hexadecimal) or any numeric base from 2 to 36.

2

Type a number

The result updates instantly as you type, using digits valid for the selected base.

FAQ

Common questions

Is my data sent anywhere?
No. The conversion runs entirely in your browser — nothing is transmitted, logged, or stored.
What happens if I enter an invalid digit for the base?
The result area shows "Invalid input for selected base" — for example, entering "9" while "octal" (base-8) is selected, since octal only uses digits 0–7.
