GUID Generator
Generate UUID / GUID values in bulk
Tool guide
Set a count (1–100) and click Generate to output RFC 4122 UUID v4 values — one per line. Copy them for test data, placeholder IDs, or distributed identifiers.
- Count:Up to 100 per batch; higher values are clamped
- Format:Standard 8-4-4-4-12 hexadecimal UUID
- Privacy: Generated entirely in your browser — nothing is uploaded
FAQ
Which UUID version is generated?
Uses crypto.randomUUID() for UUID v4; older browsers fall back to an equivalent random v4 algorithm.
Is my data uploaded?
No. Everything runs locally in your browser.
What is the difference between UUID and GUID?
GUID is Microsoft’s name for the same kind of identifier. This tool generates RFC 4122 UUID v4 values, which fit most GUID use cases directly.
How many can I generate at once?
Up to 100 per run; generate in batches if you need more.
