Convert numbers between binary, octal, decimal, hexadecimal and any base from 2 to 36 instantly, with all representations shown side by side.
The Number Base Converter converts a number between binary, octal, decimal, hexadecimal, or any custom base from 2 to 36, showing every representation side by side as you type. Enter a value in one base and the others update instantly, making it a quick reference for anyone working with binary logic, hex colour codes, or low-level programming concepts.
Rather than manually dividing by the target base and tracking remainders, or looking up a static conversion table, this tool handles arbitrary bases in real time, including uncommon ones used in specific contexts like base-36 for compact identifiers. It is a practical companion for students learning number systems and developers debugging binary or hex values.
Binary, octal, decimal and hexadecimal values are displayed together and update live, so there's no need to convert one pair of bases at a time and re-enter values manually.
Beyond the four common bases, any base from 2 to 36 can be selected, covering less common needs like base-36 encoding used in short URL identifiers or certain hashing schemes.
Manual base conversion is error-prone, especially with long binary strings. Automated conversion removes the risk of a misplaced digit or dropped remainder during manual working.
The standard manual method divides the decimal number repeatedly by 2, recording the remainder each time, then reads the remainders from bottom to top. For example, 13 divided down gives remainders 1, 0, 1, 1, which read backwards gives 1101 — the tool performs this instantly for any base pair.
One hexadecimal digit represents exactly four binary bits, so a full byte always maps to exactly two hex digits. This makes hex a compact, human-readable stand-in for binary values in memory addresses, colour codes and low-level debugging output.
The converter handles bases from 2 through 36, using the digits 0-9 and letters A-Z for bases above 10. Very large numbers are supported up to the precision limits of standard numeric representation in the browser, which comfortably covers typical programming and educational use.
Divide repeatedly by 2 and record each remainder, then read the remainders bottom to top. 13 gives 1101.
One hex digit maps exactly to four bits, so a byte is always two digits. That makes memory addresses, colour codes and bit masks far easier to read than long binary strings.
