Number Base Converter

Made for the task at hand.

Translate integer representations without floating-point precision loss. Source digits are checked against the selected base, and arbitrary-precision arithmetic supports values beyond JavaScript’s safe-integer range.

How to use

1. Enter an integer using only digits valid in its source base.
2. Set the source base from 2 to 36 and choose the target base.
3. Copy the converted integer; letters in bases above 10 are shown uppercase.
