Number Base Converter

A number base converter translates an integer between the bases programmers meet most often: decimal (base 10, what humans use), hexadecimal (base 16, common in colors and memory addresses), binary (base 2, the language of hardware), and octal (base 8, still seen in Unix file permissions). It is essential when reading low-level values or moving between representations. Enter any non-negative integer and press Convert. The tool shows all four representations at once — decimal, hexadecimal (prefixed 0x), binary, and octal — so you can copy whichever your context needs. It runs entirely in your browser with no upload, and it validates that you entered a non-negative integer. Students learning computer science use it to build intuition about how numbers are really stored. Developers use it when debugging memory addresses, interpreting hex color values, reading chmod permissions (octal), or working with network masks. Seeing all bases side by side makes the relationships click. A couple of honest notes: this handles non-negative integers; fractional bases and negative numbers are out of scope for a quick converter. And very large integers are limited by JavaScript's safe integer range, so astronomically huge values may not be exact — mention that for completeness. For AdSense readiness, write original content explaining each base with a worked example (say, converting 255), and answer a short FAQ, linking to the color converter. Useful, accurate pages are the principle behind this toolbox and the reason it is built to earn approval and traffic.
