Every tool runs entirely in your browser. Nothing you type is uploaded, stored, or logged on our servers.
The Number Base Converter converts integers between Decimal (base 10), Hexadecimal (base 16), Binary (base 2), and Octal (base 8) in real time. Select your input base, type a value, and all four representations update instantly.
Common prefixes (0x, 0b, 0o) are stripped automatically. Each output card has its own copy button and displays the appropriate prefix so you can paste directly into code.
It converts numbers between bases such as binary, octal, decimal, and hexadecimal, showing the equivalent value in each system.
No. Conversions run client-side in your browser, so nothing you enter is uploaded.
It covers the common programming bases: binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16).
Yes. Enter a value in any supported base and the equivalents in the other bases update at the same time.
Each base only allows certain digits, so entering a digit like 9 in a binary field or G in hex is invalid and flagged.
