How do you convert hex to binary?

One hex digit is exactly four bits, which makes this conversion mechanical: 4 is 0100, 8 is 1000, so the byte “48” expands to “01001000”. The converter strips 0x prefixes and whitespace before reading pairs of digits, and every pair prints as a full eight-bit group. Use it when you need to see which flag bits a hex value actually sets.

How to use the Hex to Binary

  1. 1 Paste hex in any common layout: spaced pairs, one run, or 0x-prefixed values.
  2. 2 Every byte renders as an 8-bit binary group.
  3. 3 Trace individual bits against the hex to see which flags are set.
  4. 4 Copy the bit string.

What you can use it for

  • Expanding hex into bit patterns.
  • Teaching the hex–binary relationship.
  • Preparing binary from hex data.
  • Inspecting byte values bit by bit.

Frequently asked questions

How many bits does each hex pair become?
Always eight. Each hex digit contributes four bits, so a pair like ff becomes 11111111 with no truncation of leading zeros.
Does input format matter?
No cleanup needed on your side. Prefixes, spaces and line breaks are removed before parsing, so debugger output pastes straight in.
Why do leading zeros matter in the output?
Because 8-bit alignment is what lets you read bit positions. 0x08 prints as 00001000, making it obvious bit 3 is set; trimming zeros would shift every position.
