HEX ↔ Binary Converter

Convert hexadecimal bytes to 8-bit binary groups and binary bytes back to HEX, with strict input checks and optional spacing.

Binary is grouped as 8 bits per byte. Hex is grouped as 2 digits per byte; conversions preserve exact bytes, not text encoding.

What is HEX ↔ Binary Converter?

Hexadecimal and binary are two ways to represent the same underlying bytes. Every hexadecimal byte has two digits and corresponds to a binary group of eight bits. This converter preserves byte values and supports optional spaces between bytes. It does not guess whether the bytes represent text, numbers, or machine code.

How to use this tool

  1. Select HEX → Binary or Binary → HEX.
  2. Paste complete hexadecimal bytes or 8-bit binary groups; use spaces as desired.
  3. Convert, copy, or export the exact byte representation.

Example

HEX 48 69 → Binary 01001000 01101001
