How Binary to Hex Works

Group binary digits into sets of 4 (nibbles), then convert each group to its hex equivalent.

0000

→ 0

0001

→ 1

0010

→ 2

0011

→ 3

0100

→ 4

0101

→ 5

0110

→ 6

0111

→ 7

1000

→ 8

1001

→ 9

1010

→ A

1011

→ B

1100

→ C

1101

→ D

1110

→ E

1111

→ F

How it works

Enter a binary number (string of 0s and 1s) in the input field. The converter groups bits into sets of 4 (starting from the right) and converts each group to its hexadecimal equivalent.

Binary input can include spaces for readability (e.g., "1010 1100") which are automatically ignored. The converter handles binary strings of any length using BigInt for precision.

Results display instantly as you type. The hex output includes optional "0x" prefix and uses uppercase letters (A-F). Copy the result with one click for use in code or documentation.

When You'd Actually Use This

What to Know Before Using

4-bit grouping: Each hex digit represents exactly 4 binary bits. Group binary from right to left in 4s for manual conversion.

Padding: If binary length isn't divisible by 4, leading zeros are implied. "101" becomes "0101" = 5 in hex.

Binary validation: Only 0 and 1 are valid binary digits. Any other characters are flagged as errors.

Bit order: Binary is read left-to-right with leftmost bit being most significant (big-endian convention).

Length limits: No practical limit on binary length. BigInt handles thousands of bits accurately.

Common Questions

What is 11111111 in hex?

11111111₂ = 0xFF. Group as 1111 1111, each group is F, giving FF.

How do I convert binary to hex manually?

Group bits by 4 from right. Convert each group: 0000=0, 0001=1... 1010=A, 1011=B... 1111=F. Combine results.

What if my binary has spaces?

Spaces are ignored. "1010 1100" converts the same as "10101100". Spaces can help readability for long binary strings.

Can I convert hex back to binary?

Yes. Use the hex-to-binary converter which reverses this process, expanding each hex digit to 4 binary bits.

What is 1010 in hex?

1010₂ = 0xA (decimal 10). This is a common 4-bit pattern representing the hex digit A.

How many bits in a hex digit?

Exactly 4 bits per hex digit. This is why hex is convenient - it's a compact, human-readable representation of binary.

What's 00000001 in hex?

00000001₂ = 0x01 = 1. Leading zeros don't change the value but may indicate byte width.
