The hex to binary converter translates hexadecimal (base-16) values into their binary (base-2) equivalents. Enter a hex string and see the binary result with each hex digit expanded to its four-bit representation.
Each hexadecimal digit maps to exactly four binary digits. Replace each hex digit with its four-bit binary equivalent and concatenate the groups to form the full binary number.
For example, hex 3F becomes 0011 1111 in binary. The digit 3 maps to 0011 and F maps to 1111.
Hex-to-binary conversion is essential for analysing bit patterns in hardware registers, network packet headers, and cryptographic hash outputs.
Frequently asked questions
Yes. Every hex digit maps to exactly four binary bits, even if the leading bits are zeros (for example, hex 1 becomes 0001).
Enter only the hex digits without the 0x prefix. The prefix is a programming convention, not part of the number itself.
