How do I convert binary to a UUID?

Paste a 128-bit binary string (0/1) into the tool and click Convert. It outputs a standard UUID format (8-4-4-4-12).

What format does the binary need to be in?

The binary input must be exactly 128 bits (0s and 1s). You can paste binary strings separated by new lines and the tool will convert each line into a UUID.

Can I convert multiple binary UUIDs at once?

Yes. Paste multiple 128-bit binary strings, one per line, and the tool converts each to a UUID in the same order. Invalid lines are flagged by line number.

Is this tool private?

Yes. All conversion happens locally in your browser; nothing is sent to a server or stored externally.

Why convert binary to a UUID?

Some systems store UUIDs as raw 128-bit binary values. Converting to the standard UUID string makes them easier to read, share, and troubleshoot.

Exactly 128 bits

Binary input must be 128 bits long (16 bytes). The tool validates length and characters before conversion.

Supports multiple lines

Paste multiple binary strings (one per line) and convert them all at once. Invalid lines are highlighted with line numbers.

Client-side only

Conversion happens entirely in your browser; nothing is sent to a server.

Overview

What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit value standardized by RFC 4122. It is most commonly displayed as a 36-character text string with hyphens.

Converting binary UUIDs into the standard format makes them readable and compatible with most tooling and libraries.

128 total bits (16 bytes)
Standard UUID: 36 chars (32 hex + 4 hyphens)
Binary input: 128 bits (0/1 string)
Useful for logs, databases, and binary protocols

Versions

UUID Versions Compared

All UUID versions are 128 bits, so they all map to 128-bit binary strings.

Version	Generation Method	Use Case	Requires
v1	Timestamp + MAC address	Time-ordered logging	Network interface
v2	DCE security (UID/GID)	Legacy DCE systems	System identity
v3	MD5 hash of namespace+name	Deterministic IDs	Namespace + name
v4	Random	General purpose — UUID v4 Generator →	None
v5	SHA-1 hash of namespace+name	Deterministic IDs (secure)	Namespace + name
v6	Reordered timestamp (RFC 9562)	Sortable time-based IDs	Clock + node
v7	Unix timestamp + random (RFC 9562)	Database-friendly sortable IDs	None

How It Works

How This Binary → UUID Tool Works

This tool validates that each input is a 128-bit binary string (0s and 1s), converts it into 16 bytes, and formats those bytes into a standard UUID string (8-4-4-4-12).

Everything runs locally in your browser; no data is sent to any server.

Private / client-side Instant conversion RFC 4122 compliant No external dependencies

Common Use Cases

Common reasons to convert binary UUIDs include:

Reading UUIDs from binary logs Working with binary storage formats Debugging binary protocols Mapping bitfields to human-readable IDs

FAQ

Frequently Asked Questions

Answers to common questions about converting binary to UUID.

UUIDs are 128 bits (16 bytes). This tool converts those 128 bits into the standard UUID string format.

Yes. Paste one 128-bit binary string per line and click Convert. Each valid line converts to a UUID, and invalid lines are flagged by line number.

The tool validates that the input is exactly 128 bits (0s and 1s). Lines that do not match this requirement will be marked invalid.

Yes. This tool runs entirely in your browser. Nothing is sent to a server or stored externally.
