# UUID Generator

> Generate single or bulk UUIDv4 identifiers from your browser crypto engine - never guessable.

Generate cryptographically random UUIDv4 identifiers free - bulk up to 500, UPPERCASE or hyphen-free output. All local.

- **Canonical:** https://www.ailovekit.com/dev/uuid-generator/
- **Category:** Developer Tools
- **Processing:** Runs entirely in your browser. Files are never uploaded to AiLoveKit servers.

## Identifiers You Can Trust

AiLoveKit's **UUID generator** draws randomness from crypto.getRandomValues - the same cryptographic source your browser uses for TLS - so every identifier has the full 122 bits of entropy guaranteed by RFC 4122 version 4. Generate up to 500 at once for seeding databases, test fixtures, or trace IDs.

## Output Options

- **Bulk** - 1 to 500 UUIDs, one per line.

- **UPPERCASE** - for systems that expect canonical uppercase form.

- **No hyphens** - the 32-hex form for compact storage and URLs.

## Frequently Asked Questions

**Are these real version 4 UUIDs?**

Yes - 122 random bits with the version and variant fields set per RFC 4122, sourced from crypto.getRandomValues.

**Can two generated UUIDs collide?**

In practice, no - generating a billion UUIDs gives a collision probability near zero.

**Is generation private?**

Fully local - randomness comes from your own browser, and nothing is logged or transmitted.
