Free Number Base Converter
Need to convert numbers between binary, decimal, hexadecimal, or octal? Our free Number Base Converter does it instantly โ type a value in any base and see it converted to all the others at once, live as you type.
Unlike a plain converter, this tool shows the actual working: positional-weight expansion for conversions to decimal, and repeated-division steps for decimal-to-other-base conversions โ so you can follow exactly how the answer was reached, not just copy it. Invalid digits for the chosen base (like a 2 in binary) are flagged immediately instead of silently misread.
Whether you're studying computer science, debugging low-level code, or just curious how computers represent numbers, this converter handles binary, octal, decimal, and hex conversions cleanly, with grouped digits for readability and one-click copying of the result. No sign-up, no downloads, no limits. See the About page or the FAQ for more.
