Hexadecimal to binary, explained
Each hex digit expands to exactly four binary bits, so conversion is a straight digit-by-digit lookup — f → 1111, a → 1010. Enable padding to keep the leading zeros of each nibble (useful for byte-aligned data); disable it for the shortest form. A leading 0x is accepted and ignored. Everything runs locally.
Private & free — this tool runs entirely in your browser.
