About this free number base converter tool
Convert integers between binary, octal, decimal and hexadecimal. Developer utilities inspect or transform data locally rather than contacting the address or service shown in your input. Use fictional samples while checking a format, keep credentials out of shared screenshots and validate the result against the receiving system. Successful parsing does not establish trust, security or schema correctness.
A practical example
A concrete example uses integer: 255; input base: 10. The result is Binary: 11111111 Octal: 377 Decimal: 255 Hexadecimal: FF.
Before you rely on the result
Whole integers only, up to 4,096 input digits. Fractions and prefixes such as 0x are not accepted; select the input base explicitly.
