À propos
A UUID (Universally Unique Identifier) is a 128-bit label that's practically guaranteed to be unique across systems without coordination. UUID v4 — the kind this tool generates — is built from 122 random bits plus 6 fixed bits, giving 5.3 × 10^36 possible values. Collisions are astronomically unlikely unless your random source is broken.
This tool uses the browser's built-in crypto.randomUUID() API when available and falls back to a CSPRNG-based implementation otherwise. The randomness is cryptographically strong — far better than Math.random() — so the IDs are safe for security tokens, session IDs, and primary keys.
Generate one UUID or a thousand in a single click. Each result is shown with a one-click copy button and the full hex/UUID form is preserved. No server, no analytics, no log.
