Random v4 IDs are the default for database primary keys in many stacks, test fixtures, correlation IDs in logs, and client-generated record keys before sync. They are not ordered in time — if you need sortable IDs, look at ULID or UUID v7 elsewhere.
Each line is an independent v4 string in standard hyphenated form. The cap of 100 per run keeps the tab responsive. For millions of IDs, use a script in your environment rather than a web form.
Version 4 only — not v1 MAC-based, not v7 time-ordered, no brace-wrapped Windows-only format toggle. Uniqueness is probabilistic, not a guarantee enforced by a central registry.
UUID v4 only — not v1 or v7.
Maximum 100 UUIDs per generation.
No central uniqueness guarantee.
They use crypto.randomUUID as implemented by your browser, which is suitable for v4 identifiers in normal application use.
The UI caps at 100 per click. For larger batches, loop randomUUID in your own script or REPL.
No. They exist in the output until you copy or clear the page.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
