Quick Work StudioGenerators
Version-4 unique identifiers.
The UUID Generator is a free online tool in Quick Work Studio's generators collection. Version-4 unique identifiers. A UUIDv4 is 122 random bits arranged into the standard 8-4-4-4-12 hex format, with a few fixed bits marking its version — the collision odds are astronomically small.
Generators like this are handy any time you need something random or unique on demand — a password for a new account, a placeholder value while testing, or just settling a decision. Because everything runs in your browser, nothing you generate is transmitted or logged anywhere.
Like every tool on Quick Work Studio, the UUID Generator is 100% free, requires no sign-up, and works instantly in any modern browser on desktop or mobile — it's one of 100+ tools built to save you a small chunk of time without getting in your way.

UUIDs are used as unique identifiers in databases and software systems where a guaranteed-unique ID is needed without a central authority assigning it.
