GUID Generator

FAQ

Is a GUID the same as a UUID here?+

Yes. This tool outputs RFC 4122 UUID version 4 strings — the same format commonly called a GUID in .NET and Windows documentation.

How many GUIDs can I generate?+

Up to 1,000 per batch. Use presets for common counts or type a number between 1 and 1,000.

Can I remove hyphens or use uppercase?+

Yes. Toggle Remove hyphens for a 32-character hex string, or Uppercase for canonical uppercase output. Default is lowercase with hyphens.

Is my data sent anywhere?+

No. GUID generation is fully client-side. DevTilt does not log or upload generated identifiers.

Will two batches ever repeat the same GUID?+

Collision risk for v4 UUIDs is negligible for application IDs. Regenerate if your policy requires unique values per request — this tool does not track prior batches.
