About Hex to Binary
This tool rewrites hexadecimal numbers as binary, the base 2 form computers work in. Each hex digit expands to four binary bits, and large values stay exact.
Frequently Asked Questions
Do I need to write the 0x prefix?
No. Just enter the hex digits. Upper and lower case both work, and you can separate several numbers with spaces.
Is there a limit on the size of the number?
No practical limit. Conversions use big integer math, so even very large numbers convert exactly. Separate multiple numbers with spaces.
