Integer Base Converter

Convert exact integers between bases2–36, with signed/unsigned8–64-bit ranges and two’s-complement export.

Enabling local controls…

All inputs are numeric literals, not implicit signed bit patterns: positive FF means255 and overflows signed8-bit. Negative numeric values export fixed-width two’s complement. Matching0b/0o/0x prefixes accepted; overflow never wraps.4096 UTF-8 bytes; exact BigInt arithmetic; no fractions.

Exact conversion

Edit any numeric field and convert. Editing removes old conversions.

How to use this tool

Edit any binary/octal/decimal/hex field or choose another base. Select arbitrary precision or a fixed signed/unsigned range; overflow is rejected.

When not to use it

Integer literals only,4096 UTF-8 bytes. Matching0b/0o/0x prefixes accepted. Positive inputs are numeric literals: signed8-bit FF is255 and overflows; negative numeric inputs export as fixed-width two’s complement. No silent wrap.
