uuidgen.199xc.com is a lightweight UUID generator that lets you produce different UUID versions quickly in your browser. The page stays simple and focuses on one flow: pick version & format, generate, copy or download.

Purpose

No installation needed; batch-generate UUIDs for development and testing.

How it works

v4 uses a cryptographically secure random source; v7 is time-ordered per RFC 9562.

Privacy

UUIDs are generated locally and are never uploaded or stored.

What it can do

  • Supports UUID v4 (random) and v7 (time-ordered).
  • Generate up to 1000 at a time.
  • Toggle case and choose standard / braces / URN formats.
  • Copy each one, copy all, or download as text.
  • Re-generates automatically when options change.
