Hexadecimal to decimal conversion translates base-16 numbers (using digits 0-9 and letters a-f) into the familiar base-10 numbering system we use every day. This conversion is essential in computing and programming, where hexadecimal is used as a compact notation for binary data — color codes in CSS, memory addresses, MAC addresses, and error codes are all commonly expressed in hex but often need to be understood as decimal values.
This free online converter handles everything from single hex digits to arbitrarily large hexadecimal numbers using BigInt for full precision. You can convert multiple hex values at once by entering each on a separate line, and any 0x prefix is automatically stripped. All processing runs entirely in your browser — no data is ever sent to a server, so your input stays completely private. No sign-up, no ads, just instant hex-to-decimal conversion.
