Formats, options, and limits for UUID Generator
A quick reference for how the tool works.
No uploads or files
The tool has no file upload at all. It only takes your options, so there are no file size limits.
| Option | Status |
|---|---|
| Version (v4 / v7) | Supported |
| Count | Supported |
What a UUID looks like
A UUID is a string in the form:
`xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`
Versions v4 and v7 fit this standard format; the difference is how the value is generated.
Choosing a version
- v4 — random, for general-purpose identifiers
- v7 — time-based, sorts in creation order
Verdict
UUID takes only your options — no uploads — and produces v4 or v7 UUIDs with copy-to-clipboard.
