UUID Generator

Create random UUID v4 identifiers on this page. Generate one or a list, then copy them or download a TXT file.

How to use

  1. Set how many UUIDs you need (1 to 100).
  2. Generate. Each value is a UUID v4 (the same format people often call a GUID).
  3. Copy the list or download it as a text file.

How it works

A UUID (universally unique identifier) is a 128-bit label written as 32 hex digits in five groups. GUID is the same idea under a Microsoft name; the string form matches.

Version 4 is random: 122 bits come from a cryptographic RNG, four bits mark version 4, and two bits mark the RFC 4122 variant.

This page uses crypto.randomUUID() when the browser provides it, and a standards-compatible getRandomValues fallback otherwise. The result looks like 550e8400-e29b-41d4-a716-446655440000.

These are identifiers, not secrets — do not treat a UUID as a password. UUID v1 (time-plus-node) and UUID v7 (time-ordered) are not generated here.

Formula

128-bit value
version nibble = 4
variant bits = 10xx (8, 9, a or b)
text form = 8-4-4-4-12 hexadecimal groups

Worked examples

  • One UUID

    Count 1 One UUID v4 such as 550e8400-e29b-41d4-a716-446655440000

  • A list

    Count 5, download TXT Five UUIDs, one per line, in multiconvers-uuids.txt

Useful notes

  • UUIDs are identifiers. They are not a substitute for a password.
  • Generation is local. Values are not uploaded.
  • “GUID generator” searches land here because a GUID uses the same 8-4-4-4-12 hex layout.

FAQ

What is a UUID v4?

A 128-bit random identifier defined by RFC 4122. The version digit is 4, and the variant nibble is 8, 9, a or b.

Is a GUID the same thing?

For practical purposes, yes. GUID is the common Windows name for the same 128-bit identifier written as 8-4-4-4-12 hex groups. This page generates UUID v4 values in that form.

Can I generate more than one?

Yes. Set the count from 1 to 100, then generate. Copy the list or download it as a text file.

Do you support UUID v7?

Not yet. This page only creates UUID v4.

Are UUIDs uploaded?

No. They are created in your browser and are not sent to analytics.

Can I use a UUID as a password?

No. A UUID is an identifier. Use the password generator if you need a secret.
