How do you convert hex to binary?

Replace each hex digit with its 4-bit binary equivalent, then concatenate. Example: A → 1010.

Are lowercase hex letters supported?

Yes. a–f are treated the same as A–F.

FF₁₆ = 11111111₂ (one byte, decimal 255).

Remove prefixes like 0x before converting, or paste only the hex digits.

Each hex digit always represents exactly four binary bits; padding preserves leading zeros inside a byte.
