Convert numbers between base systems
Tan Phat Digital's Base Converter tool is the perfect solution for developers, students, and professionals who need to convert numbers between popular base systems in programming and computer science. Fully supports the 6 most important base systems: Binary (Base 2) - the computer's foundational language with only 0 and 1, Octal (Base 8) - popular in Unix file permissions, Decimal (Base 10) - a familiar everyday decimal system, Hexadecimal (Base 16) - widely used in programming for CSS colors, memory addresses, and byte values, Base32 - used in TOTP authentication and encoding schemes, and Base36 - maximum alphanumeric base for URL shortening and unique IDs. Enter numbers in any base system and see the conversion results to all other systems at the same time, saving significant time compared to converting each pair. The smart swap feature allows you to quickly use the results as new input for chain conversions. Copy each result with one click on the clipboard. Validate input automatically according to the selected radix, displaying a clear error message if the input is invalid. Display uppercase results for Hex and Base36 according to standard convention. The tool handles completely offline in the browser using native JavaScript functions, does not send data to the server, ensuring security and privacy. Completely free, unlimited number of conversions, no need to register an account. Especially useful for software developers working with low-level programming, embedded systems, and binary data; students learn about computer science fundamentals and number systems; network engineers work with IP addresses and subnetting; security professionals analyze hex dumps and binary files; and anyone who needs quick number base conversions in their daily work.
Base conversion is a fundamental skill in programming and computer science. Binary is the language of computers, all data is stored in the form of 0 and 1. Hexadecimal is widely used in programming: CSS colors (#FF5733), memory addresses, byte values, and debugging. Octal appears in Unix file permissions (chmod 755). Base32 and Base36 are used in encoding and URL shortening. Understanding and converting between number systems helps developers debug more effectively, read and understand low-level code, and work with binary data.
