About This Tool


Hex to binary conversion expands each hexadecimal digit into its 4-bit binary equivalent. This reveals the underlying bit pattern that computers actually use to store and process data.

Each hex digit (0-F) converts to exactly 4 binary digits. F = 1111, A = 1010, 5 = 0101, 0 = 0000. This consistent mapping makes the conversion predictable and easy to verify.

For example, hex "FA" converts to binary "11111010": F = 1111, A = 1010. The 2-digit hex expands to 8-bit binary, showing the complete bit pattern.

This conversion is valuable when you need to analyze data at the bit level, such as understanding flags, masks, or bit fields in programming. It's also essential for digital logic design.

The tool preserves leading zeros in each nibble, ensuring the output accurately represents the hex input's bit width. This is important for fixed-width applications.

Frequently Asked Questions

Why does each hex digit become 4 binary digits?
Each hex digit can represent 16 values (0-15), which requires exactly 4 bits (2^4 = 16) to express in binary.
Are leading zeros included?
Yes, each hex digit produces exactly 4 binary digits, including any leading zeros needed.
Is hex input case-sensitive?
No, both uppercase (A-F) and lowercase (a-f) are accepted and produce the same binary output.
What about 0x prefix?
The tool accepts hex with or without the 0x prefix. It's automatically stripped for conversion.
How do I verify the conversion?
Each hex digit maps to a specific 4-bit pattern. Memorize 0=0000, F=1111, and work out others by position.
