Frequently asked questions
v4 or v7?
v4 is fully random. v7 starts with a timestamp, so IDs sort by creation time — great for databases.
Is UUID Generator free?
Yes. UUID Generator is completely free, with no sign-up, no watermark and no usage limits.
Is my data uploaded to a server?
No. UUID Generator runs entirely in your browser. Your files and text never leave your device.
Does it work offline?
Yes. After Red Cat Tools has loaded once, this tool keeps working without an internet connection. You can also install Red Cat Tools as an app.
