Base Converter

Convert integers between binary, octal, decimal, and hexadecimal.

About Base Converter

Base Converter translates signed integers across binary, octal, decimal, and hexadecimal formats instantly. It validates input digits against the selected source base and shows all target bases at once for fast comparison. This is useful in debugging, systems work, protocol inspection, and low-level programming tasks.

Why use Base Converter

  • Convert across common number bases in one view.
  • Catch invalid digits early with per-base validation.
  • Use BigInt-backed integer conversion for reliable results.

How to use Base Converter

  1. Select the source base for your input value.
  2. Enter a signed integer in that base.
  3. Read converted outputs for base 2, 8, 10, and 16.

When to use Base Converter

  • Debugging bitmasks and numeric literals.
  • Translating protocol/log values across bases.
  • Teaching number systems with side-by-side outputs.
