UUID Generator

Generate UUID v1, v4, v7, GUID, nil, and max IDs in the browser. Format with hyphens, braces, or URN, export lists as text or JSON, and decode any UUID. Nothing is uploaded.

v4 is random. V7 is time-ordered for databases. V1 uses a random node (not your MAC). Nil is all zeros; Max is all Fs.

Accepts hyphens, braces, and URN prefixes.

How it works

1

Pick a version

Choose v4 (random), v7 (time-ordered), v1, GUID formatting, nil, or max. Set count and output format.

2

Generate and export

Create IDs in this tab. Copy the list or download as text or JSON. Formatting includes hyphens, braces, and URN.

3

Decode when needed

Paste any UUID to validate it and inspect version, variant, and embedded timestamps for v1 and v7.

What is UUID Generator?

Create and format UUIDs and GUIDs entirely in your browser, export bulk lists, and decode version and timestamp details without uploading data. UUID Generator is part of Easy24’s generator toolbox. Your input stays in this tab for normal use; Easy24 does not upload that content to process it. This tool has no daily free-plan cap; use it as often as you need. Typical flow: Pick a version, count (up to 100), and formatting. Generate, then copy or download as lines, commas, or JSON. Paste any UUID into Decode to see version, variant, and timestamps for v1/v7. Related tools and reverse conversions appear on the page when a follow-up step is common.

Why use this tool

  • UUID v1, v4, v7, GUID, nil, and max generation
  • Bulk lists with newline, comma, or JSON export
  • Built-in decoder for version, variant, and timestamps
  • Runs locally with unlimited use on the free plan
  • Decode panel shows version, variant, and v1/v7 timestamps

Questions

v4 or v7?

v4 is fully random and the usual default. V7 embeds a Unix millisecond timestamp so IDs sort by time, useful for database primary keys.

Does v1 leak my MAC address?

No. This tool uses a random node with the multicast bit set, not your hardware address.

What are nil and max?

Nil is the all-zero UUID. Max is all F characters. Both are defined in RFC 9562 for special cases and tests.

Can I decode a UUID?

Yes. Paste it into Decode. For v1 and v7 the embedded timestamp is shown when present.

When to use UUID Generator

Teams and individuals use UUID Generator for everyday workflows where speed and privacy matter more than a feature-heavy suite. Generate UUID v1, v4, v7, GUID, nil, and max IDs in the browser. Treat generated secrets as sensitive even when created locally; store them in your password manager, not in chat logs. Because UUID Generator is bilingual on Easy24, the same workflow works in English or Turkish without changing how the tool behaves. Browser-first processing is the privacy default here: there is no Easy24 document inbox waiting to expire after a timeout for this workflow. This page has no daily free-plan cap, so you can run it as often as you need. When you are done, download or copy what you need, then close the tab. Related tools on the page cover common follow-up steps such as the reverse conversion or a neighboring format.
