How hex to binary conversion works
Hexadecimal is base-16, while binary is base-2. Each hex digit maps to up to four binary digits.
Example: hexadecimal 2A converts to decimal 42, then to binary 101010.
Common mistakes
- Using letters outside A-F, such as G or Z.
- Confusing a full hex color with a numeric hex value.
- Expecting leading zeros to be preserved in the displayed binary result.
- Using extremely large values without considering number precision limits.

Yes. A leading # is ignored before conversion.
Why did my hex input fail?
