About Hex to Binary

Paste one or more hexadecimal values and instantly see their binary representation. Each hex digit maps to exactly 4 binary bits, making this a common conversion in low-level programming and hardware engineering.

How to use

  1. Enter one hex number per line in the input panel (with or without 0x prefix).
  2. The binary equivalent appears instantly in the output panel.
  3. Click Copy to copy the results to your clipboard.

Frequently Asked Questions

FAQs about Hex to Binary

Why does each hex digit map to 4 binary bits?

Because hex is base-16 = 2^4. Values 0–15 can each be represented by exactly 4 binary digits (nibble): 0=0000, 1=0001, ..., F=1111.

Can I use 0x prefix?

The 0x prefix (common in C/C++/JavaScript for hex literals) is automatically stripped before conversion.

What is FF in binary?

FF hex = 11111111 binary — eight 1-bits, the maximum value of one byte (255 decimal).

Is hex case-sensitive?

No. This tool accepts both uppercase (A–F) and lowercase (a–f) hex digits.

Can I convert multiple values at once?

Yes. Enter one hex value per line and the tool will convert each one individually.
