Hex to Binary Converter

Why Use Our Hex to Binary Tool?

Hexadecimal (Base-16) is the standard for representing large binary numbers in computing, but systems process instructions in Binary (Base-2). Our Hex to Binary Converter bridges this gap instantly. It is an essential tool for embedded systems engineers, software developers, and computer science students needing to visualize bit patterns, flags, and memory addresses.

Unlike server-side converters, this tool runs locally in your browser via JavaScript. This means your data never leaves your device—critical when working with proprietary code, API keys, or sensitive memory dumps.

How to Convert Hex to Binary

1. Input Data: Paste your hex string into the text area. The tool accepts raw hex (e.g., 1F) or formatted hex (e.g., 0x1F).
2. Customize Output: Toggle "Add spaces" to group bits into readable bytes (8-bit chunks) or "Add 0b prefix" for code-ready syntax.
3. Get Results: Click "Convert" to see the binary equivalent immediately. Use the "Copy" button to grab the output without selection errors.

Frequently Asked Questions

How do I convert hex to binary?

Translate each hexadecimal digit into its 4-bit binary equivalent. For example, 'A' becomes '1010' and '5' becomes '0101'. Join these 4-bit groups (nibbles) together to form the final binary string.

What is FF in binary?

FF converts to 11111111. In hexadecimal, 'F' represents the value 15, which is '1111' in binary. Two 'F's together form a full 8-bit byte set to all ones.

What is 0x1 in binary code?

The '0x' prefix denotes a hexadecimal number. The value '1' translates to 0001 in binary (or 00000001 when padded to a byte).

How do you convert hex FF216 to binary?

To convert FF216, map each digit to binary: F=1111, F=1111, 2=0010, 1=0001, 6=0110. The result is 11111111001000010110.

What is the binary conversion of 11111111?

11111111 is the binary representation of the hexadecimal value FF (or decimal 255). It consists of two 4-bit groups of '1111', each corresponding to the hex digit 'F'.
