About this tool
UUID v4 uses cryptographic randomness. UUID v7 includes a millisecond timestamp and is roughly time ordered. UUIDs are identifiers, not passwords or authorization credentials. Generated values stay in page memory and cannot be recovered after clearing or closing. Only run status, duration, count and copy/download events are reported.
How to use
- Choose a UUID version and quantity.
- Generate locally with progress based on completed items.
- Change case or hyphens instantly, copy one or all, or download TXT / CSV.
Frequently asked questions
Are generated values uploaded?
No. Only run status, count, duration and whether results were copied or downloaded are reported. UUID values are not sent to this site or third parties.
Are duplicates impossible?
Standard UUID algorithms and browser cryptographic randomness make collisions extremely unlikely, but not impossible. Keep database uniqueness constraints. v7 contains time information and is not a secret.
