FAQ

What does padding mean?

With width 4, number 1 outputs as 0001 so every code has equal length for sorting; set 0 to disable.

What is the maximum count?

Up to 100k per run; generate in batches beyond that. Results can be copied or downloaded as TXT.

Will my data be uploaded?

No, all generation runs locally in your browser.
