How to use the uuid generator
Version 4 UUIDs provide randomly generated identifiers for records, test fixtures, and distributed workflows. This generator uses crypto.randomUUID and permits one to one thousand identifiers per batch. Results use the standard lowercase hexadecimal representation with hyphens. Randomness makes collisions extremely unlikely but does not replace database uniqueness constraints or make an identifier an authorization credential.
Work directly in the input area at the top of this page and choose the settings that match your task. Run the action to see the output separately from your original input. Start with a small example whose result you can check, then process the value you actually need. Changing an input clears an older result so it cannot be mistaken for a fresh conversion.
Processing runs in your browser. This tool does not send your input to a conversion server, create an account history, or save the input in browser storage. A copied result remains subject to your device clipboard settings, while a downloaded file stays on your device until you remove it. Anyone with access to your screen or browser can still see the information you enter.
Use Copy for text output or Download for a local file. If clipboard access is unavailable, select the output and copy it manually. Clear removes the current result and any main text or file input; settings remain available for another run. Keep original files and important values until you have checked that the output works in the application where you intend to use it.
Frequently asked questions
Does this work offline?
After the page has loaded, the conversion itself needs no external service. Some browser security features require HTTPS or localhost. Save results before leaving the page; there is no account library.
Why should I check the output?
Input conventions and downstream software differ. Review units, character encoding, and chosen settings before using results in an automated workflow. An output that is valid here may still be unsuitable for a particular application.
