Debugging registers, parsing color components, inspecting permission bits, or reading network masks often means converting integers between binary, octal, decimal, and hexadecimal — easy to get wrong in your head. This tool converts an integer between any base from 2 to 36 locally in your browser, with exact big-integer math. Your input and computation stay on your machine; no numbers are uploaded, ideal when dealing with internal addresses or key fragments. Tip: Bookmark this tool for quick access whenever you need format conversion. All processing happens locally in your browser — no data upload, so feel free to paste sensitive content.
How to Use
- Open the Integer Base Converter tool page
- Enter or paste your data into the input area
- View the real-time results and use the copy button to get the output
Use Cases
- Read registers — Convert a hex register value to binary to inspect each flag bit.
- Decode permissions — Turn Linux octal 755 into bits to check read/write/execute settings.
- Color debugging — Convert hex color components to decimal to compare with RGB values.
- Protocol decoding — Convert captured hex bytes to decimal to match protocol field meanings.
- Practice problems — Quickly verify base-conversion answers while studying or drilling.
- IP address math — Convert between dotted-decimal IPv4 and 32-bit integer for subnet calculations or CIDR range comparisons.
- Memory address debugging — Translate hex memory addresses from crash dumps or debugger output to decimal for offset calculations.
FAQ
Which base range is supported?
Any conversion between base 2 and base 36. Bases above 10 use letters a-z, so hex uses a-f and base 36 can use up to z.
Can it handle very large numbers?
Yes. It uses big-integer arithmetic with no 32/64-bit limit, so numbers dozens of digits long convert exactly without losing precision.
Are decimals or negatives supported?
It targets integers. A leading minus is usually recognized, but cross-base fractional conversion is limited by representation, so use it for integers.
What if I include spaces or a prefix?
Common 0x/0b prefixes and surrounding spaces are generally tolerated, but characters outside the chosen base raise an error — check you picked the right source base.
How does this differ from the color converter?
This does pure numeric base conversion only. To convert between HEX, RGB, and HSL color formats, use our color format converter.
Any browser compatibility requirements?
This tool works in all modern browsers (Chrome, Firefox, Edge, Safari). No plugins or extensions required.
Can I use it offline?
After initial load, most features work offline. The core logic runs entirely in your browser with no network dependency.
