What this utility does
Convert hexadecimal digits to binary while preserving leading hexadecimal zeroes as four-bit groups.
Input and output contract
Accepts unsigned hexadecimal digits up to 4,096 characters, with optional 0x prefix, spaces, and underscores. A binary string containing four bits for every input hex digit.
Important limitations
Negative numbers are not accepted because fixed-width signed binary representation would require an explicit bit width.
SaveEditor.com implements this utility as a deterministic browser-local operation. The conversion result depends only on the explicit input and selected options; it does not infer a game format or silently modify unrelated data.
