Frequently Asked Questions
Common questions about UUID Generator
UUID v4 is fully random, which is great for unpredictability but not sortable. UUID v7 embeds a Unix millisecond timestamp in its leading bits, so v7 IDs are time-ordered and index much better in databases while still containing random bits for uniqueness.
Yes. Version 4 and the random portions of version 7 use the browser's Web Crypto API (crypto.getRandomValues), which is a cryptographically secure random number generator. The tool falls back to Math.random only if Web Crypto is unavailable.
Completely. Generation happens 100% in your browser with JavaScript. No UUID is ever transmitted, logged, or stored on a server. You can confirm this in your browser's network tab — there are zero outbound requests.
Yes. Enter any count and the tool produces that many UUIDs at once, with a copy button on each row and a Copy all button to grab the whole newline-separated list.
