Why this tool is useful
Use this converter when logs, binary APIs or database fields display the same fixed-width bits with different signedness and you must reconcile values without precision loss.

Signed and Unsigned Integer Converter
Reinterpret decimal integers between signed two's-complement and unsigned representations at an explicit 8-, 16-, 32- or 64-bit width.
Ready. Your working data stays in this browser.
How it works
Signed input is range-checked and mapped modulo 2^width; unsigned input is bounded to the same bit pattern and interpreted by testing its most significant bit.
Practical example
At 8 bits, signed -1 and unsigned 255 share hexadecimal 0xFF and binary 11111111, while unsigned 128 reinterprets as signed -128.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
