About this tool

The PixelForge Number Base Converter instantly converts integers between binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16). All four representations update simultaneously so you can see the same number in every base at once. This is an essential tool for programmers working with bitwise operations, memory addresses, colour codes, permission flags, and low-level data.
