Number Base Converter
Type a number in any base and see it converted to binary, octal, decimal, and hex simultaneously. Shows ASCII character for printable values.
How it works
Enter a number in any of the four supported bases — binary (base 2), octal (base 8), decimal (base 10), or hexadecimal (base 16) — and the other three representations update in real time. The conversion uses JavaScript's built-in integer parsing so results are immediate and accurate.
When the decimal value falls within the printable ASCII range (32–126), the corresponding character is displayed alongside the numeric conversions. This is especially useful when working with character codes, protocol debugging, or low-level data inspection.
All processing happens locally in your browser. This makes the tool useful for quick lookups during programming, homework, or embedded systems work without needing to open a terminal or REPL.
