Hex to Binary Converter – Convert Hexadecimal to Binary

Hexadecimal (hex) is base-16 notation using digits 0–9 and letters A–F.

It is a compact way to write binary data because each hex digit maps to four bits.

• Enter hex digits in the input field.
• View the full binary expansion in the output.
• Copy or download the bit string.
• Cross-check with Binary to Hex Converter.

• Split the hex string into individual digits.
• Convert each digit to four bits.
• Join the bit groups — left digit = most significant nibble.

Each hex digit and its 4-bit binary value:

For each hex digit h:

• Look up 4-bit pattern for h (0→0000 … F→1111).
• Concatenate patterns left to right.
• Optional: strip leading zeros only when you know the required bit width.

• Reading memory dumps and opcode listings.
• Interpreting color and binary file headers.
• Network packet hex views (Wireshark-style study).

• Addresses are often shown in hex (e.g. 0x7FFE).
• Each address step can correspond to one byte.
• Binary expansion shows the exact bit pattern stored at that location.
