How it works
- Choose a count. Enter how many UUIDs you need (1 to 1000).
- Generate. They appear instantly, one per line, ready to copy.
- Copy them. Use Copy all, or tweak format in Advanced options first.
About this tool
Generate version-4 UUIDs — the random 128-bit identifiers used for database keys, request IDs, file names and anything that needs to be unique without a central counter. Pick how many you need and they appear instantly, generated with your browser’s cryptographic random source (not a weak Math.random fallback where the secure API is available). Advanced options let you uppercase them or strip the hyphens for systems that want a compact 32-character form.
What people use it for
- Create unique database or primary keys
- Generate request/correlation IDs for logs
- Make unique file or object names
- Bulk-generate test identifiers
សំណួរដែលសួរញឹកញាប់
Version 4 — random. The vast majority of UUID use-cases want v4 because it needs no coordination and carries no machine or timestamp information.
They use the browser’s crypto.randomUUID / getRandomValues where available, which is cryptographically strong, with a Math.random fallback only on very old browsers.
No. They are generated locally in your browser, so nothing is transmitted or kept.
Practically never. A v4 UUID has 122 random bits; you would need to generate billions before a collision becomes remotely likely.
Yes — open Advanced options to uppercase them or remove the hyphens for the compact 32-character form some systems expect.
Up to 1000 per click. For more, generate in batches and copy each set.
Yes — UUID Generator is completely free, with no watermark on the output and no credit card required.
Yes. It runs in your browser, so UUID Generator works on phones and tablets as well as desktop — there is no app to install.
No. UUID Generator works with no signup at all; an optional free account only exists to unlock higher usage limits.
Usually just a few seconds for a typical file — UUID Generator starts working the moment you give it your input.
