What does UUID Generator do?

It creates unique identifiers (UUIDs) — 128-bit strings used to label things without collisions. It supports v4 (random) and v7 (time-ordered) versions and lets you generate several at once.

Common uses

  • Creating database record IDs
  • Generating unique keys for APIs or files
  • Making test data with unique, non-conflicting identifiers

Key features

  • UUID v4 and v7 — choose the version you need
  • Multiple at once — generate a batch in one step
  • Copy to clipboard — copy results with one click

How it works

You pick the version and count, and the tool produces UUIDs you can copy. Everything runs locally in your browser.

v4 vs v7

  • UUID v4 — completely random; great for general use
  • UUID v7 — time-ordered; sorts chronologically, useful for databases

Verdict

UUID Generator produces v4 and v7 identifiers in batches. Open UUID and generate your IDs — free and private.
