UUID generator
Generate UUID v4 and short URL-safe random tokens with the Web Crypto API.
Your data never leaves the browser.
How it works
- A UUID v4 and short token are ready when the page loads.
- Copy either value, or generate new ones.
- Tokens use cryptographically strong randomness in the browser.
FAQ
- Is this UUID v4?
- Yes — via crypto.randomUUID() in supporting browsers.
- Are tokens logged on a server?
- No. Generation is entirely local.
