About this generator
- UUIDs are created with the Web Crypto API when available and stay inside your browser.
- URN formatting forces lowercase output and always keeps hyphens to match the RFC 4122 specification.
- Bulk copy collects the currently displayed formatting, including braces or hyphenless styles.
