Hex to Binary

Convert base-16 values into binary and compare the matching decimal and octal forms.

What does Hex to Binary do?

Hex to Binary expands hexadecimal digits into their 4-bit binary representation.

  • Primary use: Hex to Binary expands hexadecimal digits into their 4-bit binary representation.
  • Key technical fact: A 2-digit hex byte such as FF maps to 11111111, or decimal 255.
  • Practical check: Check accepted digits, ranges, signs, prefixes, and rounding before copying the converted value into code.

Expand hexadecimal values into binary bits

Hex to Binary turns base-16 input into base-2 output and also shows the equivalent decimal and octal values. It is useful for inspecting masks, bytes, packed flags, hashes, and low-level constants.

Hex input should use digits 0-9 and letters A-F; case does not matter, and whitespace is ignored. Each hex digit represents four bits, but leading zeros may need to be added back for fixed-width values.

How to use

  1. Type or paste a hexadecimal value into the input field.
  2. Review the binary result and the matching decimal and octal outputs.
  3. Copy the binary value, or clear the form before converting another hex value.

What is hex to binary conversion?

Hex to binary conversion expands hexadecimal notation back into bits. Because one hex digit maps to four binary digits, hex is a compact way to write binary data while still allowing exact bit-level inspection.

Input notes

Remove non-numeric labels and prefixes such as 0x unless accepted by the tool. For bytes, addresses, and registers, verify whether leading zeros are required in the final binary display.

Example

The hex byte FF expands to eight binary ones:

--- Hex Input ---
FF

--- Binary ---
11111111

--- Decimal ---
255

--- Octal ---
377

MCP integration

MCP (Model Context Protocol) lets AI agents and apps discover and run Coding.Tools utilities for repeatable conversions, formatting, hashing, and generation workflows.

MCP tool name: hex-to-binary

MCP endpoint: https://coding.tools/mcp

Call tools/list first. Each tool entry includes inputSchema, outputSchema, and examples so an AI agent or client can build valid arguments without guessing.

For tools/call, read result.content[0].text for the display value and result.structuredContent for machine parsing. Tool-level failures return isError: true; protocol failures return a JSON-RPC error.

Example tools/call request:

curl -s https://coding.tools/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "MCP-Protocol-Version: 2025-06-18" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"hex-to-binary","arguments":{"input":"F0A"}}}'

Most text and data tools accept an input string plus optional options. Browser-only image tools are listed for discovery and return a web UI link when they need browser image APIs.
