Private by design
Your files are opened and processed by your browser on this device. They are never uploaded to openWorkstand or anyone else, so the UUID Generator is safe for contracts, IDs, photos and work documents, and it keeps working offline once the page has loaded. How local processing works
When to use the UUID Generator
- Create IDs for database rows.
- Generate test data.
- Create unique file names.
Troubleshooting
The file does not open
Check that it is one of the supported formats above and opens in another app. Damaged files and password-protected PDFs cannot be read until they are repaired or unlocked.
It is slow or stops on a very large file
Everything runs on your device, so speed depends on its memory. Close other tabs, use a computer rather than a phone, or split the file into smaller parts first.
The download did not start
Look for your browser’s download bar or icon. Some browsers ask once before a site may download files; allow it and click the button again.
Frequently asked questions
Which version should I use?
v4 for uniqueness only, v7 for database keys because it sorts by creation time.
Keep working with the result
After you download, choose “Save to Workstand” to keep the result in a folder on your computer, attach it to a project and create a follow-up task. It is saved by your browser, not uploaded.
