{ } How it works
UUID Generator works on the options you set. Adjust the options, then select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.
Input
- How many — a value (default: "1")
Output
TXT text — copy or download it from the Output panel.
{ } Common uses
- Get an identifier for a record, a test fixture or a correlation id.
- Generate a batch of keys for seeding data.
- Produce an id with no coordination between systems.
{ } Limitations
- These are version 4 UUIDs — random, not ordered. Two rows created a second apart sort arbitrarily, which matters if you were hoping to use the id as a sort key.
- Up to 100 at a time, one per line.
{ } FAQ
Is my data uploaded to a server?
No. Everything runs locally in your browser — your files never leave your device.
Can I process more than one file at once?
This tool works on one input at a time.
Is this tool free?
Yes — it’s completely free and needs no sign-up.
Could I ever get a duplicate?
In practice, no. A version 4 UUID has 122 random bits, so collisions are not something to design around.
