UUID Generator
Generate standard UUIDs online. This page uses random UUID v4 with 122 random bits and the familiar 36-character shape.
Generated IDs
How this ID is built
- Layout
- UUID v4: 8-4-4-4-12 hexadecimal groups with RFC variant bits.
- Entropy
- 122 random bits; the version and variant consume 6 bits of the 128-bit value.
- Time
- No timestamp or device data is encoded.
- Collision risk
- The birthday bound for 122 random bits is negligible for ordinary app, test and database IDs.

Your IDs are generated locally with strong browser randomness. Nothing is sent to BroBroGo.
FAQ
What kind of UUID does this page generate?
It generates UUID v4 values: random UUIDs with the standard hyphenated shape. Use the UUID v4 page when you want the same engine with v4-focused details.
Are the UUIDs sent to a server?
No. Generation happens in your browser with the Web Crypto API, so the values stay on your device.
