Number Base Converter — Computers represent numbers in different bases. Decimal (base 10) is what humans use. Binary (base 2) is what computers actually use internally. Octal (base 8) and hexadecimal (base 16) are compact ways to write binary, used in file permissions, color codes, memory addresses, and more.
