Frequently Asked Questions

What is a number base?

A number base (or radix) defines how many unique digits exist in an numeral system. Base 2 (binary) uses 0–1, base 8 (octal) uses 0–7, base 10 (decimal) uses 0–9, and base 16 (hexadecimal) uses 0–9 and A–F.

Are hexadecimal letters case-sensitive?

No. Both uppercase (A–F) and lowercase (a–f) are accepted as input. The output is always displayed in uppercase.

Is the conversion done locally?

Yes. All conversions happen entirely in your browser. No data is sent to any server.
