Good to know

Where is my data processed?

Your browser performs the operation. Input stays in page memory. Markdown draft saving is available when you explicitly enable it on this device.

Which UUID version does this generate?

The generator creates UUID v4 identifiers using the browser's cryptographic random source. Each uses the standard hyphenated UUID format.

How many UUIDs can I generate at once?

Choose 1 to 1,000 with the count slider. You can copy the complete list or download a text file containing one UUID per line.
