Does the input need to be padded to 8 bits?

No. The tool pads the input on the left with zeros if the total bit count is not a multiple of 4. For example, "101" becomes "0101" = 5 hex.

Can I enter a continuous string without spaces?

Yes. You can enter a continuous stream like 0100100001101001 and the tool automatically groups it into nibbles for conversion.

What characters are allowed in the input?

Only 0 and 1. Spaces and newlines are ignored. Any other character is flagged as an error and conversion is halted.

How is the output formatted?

Hex digits are grouped into byte pairs (two nibbles) separated by spaces by default — e.g. 48 65 6C. You can toggle to remove spaces or switch case.

Is there a length limit?

The tool handles up to 8 192 bits (1 024 bytes) in a single pass. Longer inputs are truncated with a warning.

How do I convert binary to hex?

Split the bit string into groups of 4 bits (nibbles), then map each nibble to one hex digit (0000=0 … 1111=F). Example: 1010111 pads to 0101 0111 = 57 hex. This tool does that automatically as you type.

Summary

This tool converts binary bit strings — either space-separated 8-bit bytes or a continuous stream of 0s and 1s — into their hexadecimal representation. It processes input in real time and supports both uppercase and lowercase hex output, making it handy for low-level debugging, data encoding tasks, and learning number systems.

How it works

Enter or paste a binary string (e.g. 01001000 01101001) into the input field.
The tool strips whitespace and splits the bit string into 4-bit nibbles.
Each nibble is mapped to its hexadecimal digit (0–9, A–F).
Nibble pairs are grouped into bytes separated by spaces for readability.
Toggle uppercase or lowercase output, or copy the result with one click.

Use cases

Verify binary payloads from network packet captures.
Debug embedded firmware output displayed as raw bit strings.
Learn and practice binary–hex conversions for computer science coursework.
Convert binary data from logic analyzers to a human-readable hex dump.
Cross-check manual hex calculations against a reference tool.
Translate binary-encoded ASCII text to its hex escape sequences.
