Multi-Base Number Converter
Converts between any two bases from 2 to 36, going beyond the usual four. Base 36 is the practical ceiling because it uses all ten digits plus all twenty-six letters — there are no conventional symbols beyond that.

What the Multi-Base Number Converter does
Unusual bases turn up more often than you would expect. Base 36 is used to compress numeric IDs into short alphanumeric strings for URLs, and base 32 appears in encoding schemes that need to avoid visually similar characters.
How it works
Using the Multi-Base Number Converter
- 1Enter the number to convert.
- 2Set the base it is currently written in.

- 4The value is parsed from the source base and re-rendered in the target base.
- 5Digits above 9 use letters, so base 16 uses A-F and base 36 runs to Z.
