How to use Number Base Converter

Enter a value in any base field and the binary, octal, decimal and hex equivalents update live. Copy whichever representation you need.

Frequently asked questions

Which bases are supported?

Binary (base 2), octal (base 8), decimal (base 10) and hexadecimal (base 16), all converted at once.

Can I convert hex back to decimal?

Yes — type into the hex field and the decimal, octal and binary values update automatically.

Does it handle large numbers?

It converts standard integer values; very large numbers may exceed JavaScript's safe integer range and lose precision.
