ADVERT
Base Converter
Convert numbers between bases 2-36, including binary, octal, decimal, and hexadecimal, with clear formatting for long values and developer-friendly output.
How to use this tool
- Set source and target bases, then choose formatting options like grouping, prefixes, and letter case.
- Enter an integer value and review the converted output plus common-base equivalents.
- Copy the result or export a JSON report for debugging, QA, or documentation handoff.
Precision and validation
- Conversion uses BigInt to keep large integer math exact.
- Input digits are validated against the resolved source base.
- Optional auto-detection supports 0x, 0b, and 0o prefixed values.
Formatting controls
- Grouping makes long outputs easier to scan in binary and hexadecimal forms.
- Prefix and uppercase options help align output with coding standards.
- Common-base results reduce repetitive manual conversions during development.
