How it works
Replace each hex digit with its fixed 4-bit pattern without going through decimal.
How to use Hex to Binary Converter
- Enter hex digits (optional 0x).
- Read zero-padded binary per nibble.
- Validate length against expected word size (8, 16, 32).
Worked examples
Concrete numbers and cases you can check against the tool above.
Hex A5
A=1010, 5=0101 → 10100101 binary.
When to use Hex to Binary Converter
Datasheets list registers in hex while bus analyzers show bits. Expansion makes bit positions explicit.
Common use cases
- Map a hex opcode to individual control bits.
- Verify #FF0000 red channel is 11111111 in binary.
Inputs and outputs
- Hexadecimal strings
- Optional 0x prefix

Frequently asked questions
- Case sensitive?
- A–F and a–f are equivalent.
- Odd-length hex?
- Valid — leading zero nibble may be implied (e.g. F = 1111).
- Spaces in input?
- Many tools strip spaces; byte pairs like FF AA are common.
