Four everyday conversions in a single developer tool
The Universal Converter gathers small but frequent conversion tasks into one place. Inspect the byte representation of text, switch between number bases, decode binary, and write dates as Roman numerals — all from one set of tabs, which is handy for debugging and learning.
What's included
Base converter
Converts among binary, octal, decimal, and hex by choosing an input and output base.
Binary decoder
Restores binary to decimal, hexadecimal, and ASCII text at once.
Date → Roman numerals
Writes the year, month, and day each as Roman numerals.
How to use
- Pick the converter you need from the tabs at the top.
- Enter a value and the result appears instantly.
- Base and binary converters show 'Invalid input' when the format does not match.
Frequently asked questions
Which encoding does the text converter use?
It uses each character's Unicode code point. Basic ASCII characters fit in 8 bits; others are shown by their code point value.
Can I turn binary back into text?
Yes. The binary decoder groups bits into bytes of 8 and restores them to ASCII text. Spaces are ignored.
Do Roman numerals support zero or negatives?
The Roman numeral system has no symbol for zero or negative numbers. This tool converts positive integers (year, month, day) only.
This tool is for general conversion and learning. Verify results independently for critical data processing.
