Simple by design

From file to result in three steps

  1. 1

    Select Generate UUID; no input is required.

  2. 2

    Review the five generated identifiers.

  3. 3

    Copy or download the list, or generate a new batch.

Practical guidance

When to use Generate UUID

Best for

Creating random identifiers for test data, records or application development.

What you get

Five UUID v4 strings, one per line, generated with the browser’s cryptographic random UUID API.

Useful tip

Use a unique database constraint when uniqueness must be enforced. Random identifiers do not replace access controls.

Use UUIDs as identifiers

A UUID v4 contains hexadecimal characters grouped with hyphens in an 8-4-4-4-12 pattern. It does not encode a creation timestamp or record details. Store the identifier with the record it names; its randomness alone does not authorize access to that record.

Frequently asked questions

Which UUID version does this generate?+

It generates random UUID version 4 identifiers, also commonly called GUIDs.

Can I request a different batch size?+

The current workspace creates five UUIDs per run. Run it again for another batch.

Does my file leave my device?+

No. This tool processes your file inside your browser and does not send its contents, name or metadata to Filemivo.

Is Generate UUID free?+

Yes. It is free to use and has no artificial file-size limit. Your browser and device memory determine the practical limit.
